Hi there! Excuse me, but I am a bit bewildered; should I really have to
give cabal --force-reinstalls to upgrade yesod to the new version
1.1.0.2? It says a lot of packages are likely to be broken, as per the
paste http://pastebin.com/cYdZkShu.
I was under the impression I had RTFM, but maybe I have missed something?

I strongly suggest not to use --upgrade-dependencies. It's probably
unavoidable to break *some* (Yesod-related) packages for a framework
with as many dependencies as Yesod has, unless you use sandboxing. But
you shouldn't go ahead installing something if packages like
"bin-package-db" or "ghc" appear among the ones that are going to be
broken. I've just tested that starting from the 2012.2.0.0 platform
and yesod-platform-1.0.4.2, a simple
$ cabal install --dry-run yesod
yields

Use --force-reinstalls if you want to install anyway.
for me, which looks reasonably safe to do with --force-reinstalls.
Cheers,
Andres

Hello,
I ran into some dependency issues with cabal/ghc and could not find any
solution on the internet.
ghc-pkg check returns nothing, I suppose this is a good thing.
But ghc -v returns:

--------------------------
This looks really scary to me. I already reinstalled GHC completely but
it didn't change anything.
Is there anything I can do?
Thank you in advance.
