You don't have to stick to the supplied packages though, you can
create your own.  

Arch linux:
The cabal2arch command is used to create the package, then I guess you
can submit it to the AUR database.

Gentoo:
hackport merge pkgname

Then often the only thing that is required is to edit the ebuild
and either:

(1) remove the lower range bound
or
(2) remove the upper range bound
or
(3) specify the range check to something like:
=dev-haskell/attoparsec-0.9*

As gentoo can not handle having more than 1 range check dependency in
the ebuild.  Your created ebuilds can be installed in your own overlay
if you are not ready to publish them yet, say in
/usr/local/portage/
or you can fork:

https://github.com/gentoo-haskell/gentoo-haskell

Use git rebase to rebase your commits into a linear history, and
submit a pull request (which might require tweaking to be accepted)

The Gentoo haskell overlay is currently on ghc 7.0.4 with the
latest haskell platform.  When ghc was bumped to 7.0.4 earlier
this week, I just ran:

haskell-updater

and it rebuilt hundreds of Haskell packages with the new ghc.

Gentoo supports live ebuilds.  For example, to install
Cloud Haskell from github:

emerge -a dev-haskell/remote

Normally there are other considerations on which linux distribution to use,
like:

(1) Ease of installation and maintenance of the operating system.
Gentoo is difficult to install and maintain, it requires learning to be
a Linux expert.

(2) Gentoo is a source based distribution.  This offers more flexibility,
however it also means you need a powerful machine.  For a notebook
I think it should be a games machine or workstation notebook in
order to be chunky and have good cooling.

Fedora, Debian, FreeBSD:

I don't use them, however I think they have very good support for
Haskell packaging.  For example, Fedora updates the haddock documentation
index as pkgs are installed and removed (on Gentoo you need to run your
own script manually to update the haddock documentation index.
The haddock documentation is built with these use flags: doc hscolour).

http://fedoraproject.org/wiki/Packaging:Haskell

If the os distribution is missing a package that you need, then I think
you can create and pkg it yourself.

If you are going to install the haskell platform and then use Cabal it really 
does not matter. Any of the current distros work just fine.

On the other hand if you want to stick to supplied packages then you would be 
best served looking at the package lists and making your mind up from there.

Re: [Haskell-cafe] Haskell *interpreter* on iPad? (Scheme and Ocaml are there)

[Jack Henahan]

Oh, wow, I'd never seen gambitREPL, just the (pretty terrible) iScheme. That's 
pretty neat. It's probably quite doable, then, but the dev would either be 
forced into Hugs, or they'd have to implement a more portable GHC. Does such a 
thing exist already?

Re: [Haskell-cafe] Haskell *interpreter* on iPad? (Scheme and Ocaml are there)

[Don Stewart]

Oh, Scheme is trivial to implement, when compared with Haskell. So
people write it from scratch as a tutorial exercise.

Haskell isn't trivial to implement from scratch, so instead we port
existing implementations mostly.

That means really, porting Hugs or GHC. And you've been pointed at examples.

I think people are clearly keen for this, now it is a small matter of
programming talent and will.

Re: [Haskell-cafe] Haskell *interpreter* on iPad? (Scheme and Ocaml are there)

[John Velman]

Well, I'm not interested in a lisp interpreter written in Haskell.  Nor am
I (at the moment) interested in writing an iPad app in Haskell.

I changed the subject to clarify.

What I would like to see is A Haskell Interpreter on the iPad.  

To further emphasize, I'd like to type in (or paste in) Haskell code and
have it executed on the iPad.  To reiterate:  Something like Hugs, or ghci
on the iPad.

By the way, there are three Scheme interpreters in the iPad app store.  In
addition to the two I previously mentioned, there is iScheme.

[Haskell-cafe] Haskell on iPad? (Scheme and Ocaml are there)

[John Velman]

There are (at least) two Scheme interpreters for iPad at the iTunes store:
PixieScheme and GambitREPL.  Both allow entry of scripts, by typing or
pasting.  The Gambit community is very busy trying to expand the usefulness
of their interpreter.  Both have pretty good interfaces.

There is also an Ocaml app, but I don't know or want to know Ocaml, and the
interface looks very unfriendly.

I'd really like to have something like this in Haskell, in the "education"
pot, as is the GambitREPL.  Hugs is written in C, if I recall correctly.
Would it be possible to compile Hugs for the iPad processor, taking out
enough system calls to make it acceptable?
