I have a very basic usage pattern and installation on a few machines, and yet
continually run into the often discussed cabal-maze of problems on all of them.
I have read all of the many explanations of why it is a hard problem, but so
far the only solution I have heard for repair is to erase the installed library
files, and start over. This can be hard if one has any external libraries
installed which were themselves a lot of work to get functioning, an example
are graphics libraries (like WxWin).
Has anyone created any scripts which would note everything which is installed,
clear out all libraries, and then try to re-install everything? (This is on
Windows....) Or would this typically just run into the same problems?
Doing a cabal update, it notes a new version of cabal -install, so trying that
fails, and now it looks like cabal itself is broken (no installs work).
Any short-term \remedies, and/or long term better approaches?
>cabal update
Downloading the latest package list from hackage.haskell.org
Skipping download: Local and remote files match.
Note: there is a new version of cabal-install available.
To upgrade, run: cabal install cabal-install
>cabal install cabal-install

Backjump limit reached (change with --max-backjumps).
Note: when using a sandbox, all packages are required to have consistent
dependencies. Try reinstalling/unregistering the offending packages or
recreating the sandbox.

A method that usually works is as follows:
md CabalInstall
cd CabalInstall
cabal sandbox init
cabal install cabal-install
Then copy CabalInstall\.cabal-sandbox\bin\cabal.exe to the location of the
old cabal.exe (probably something like "C:\Program Files\Haskell
Platform\2014.2.0.0\lib\extralibs\bin\"
(Maybe rename the old cabal.exe to cabal-1.20.0.4.exe (or something
similar) first)
Check with
cabal --version
if the correct version of cabal.exe is run.
If you are using a sandbox, all locally installed packages are ignored, so
there is less chance of dependency problems.

Henk-Jan van Tuyl

I've run into problems like this before; there seems to be some issues with
certain versions of llvm. I got around it by compiling arithmoi without llvm
support:
$ cabal install Diagrams --constrain "arithmoi -llvm"

If you're on Windows install development environments outside the Programs
