[TL;DR: there's a concrete question at the bottom.]
Once again I find myself in the pleasant situation where the slings and arrows of life in general are slightly less intense, and I manage to find a few spare minutes and some free brain cycles to dedicate to Haskell.
Why not try GHC 7.0.3? (after all, GHC 7 has been out for a good few months, so the teething troubles should have passed by now), and there's a lovely new Haskell Platform 2011.2.0.1 to go with it, so, maybe this time, I'll actually be able to use some of the libraries that I tried and failed to install during my last period of Haskell study.
The two computers I have available for playing with Haskell run OS X Leopard (10.5), and Ubuntu Natty (11.04).
I can't say anything about OS X, but I've been using ghc 7.0.3 under Ubuntu. I just cabal-install what I want - and use apt-get for any required C libraries. To set up cabal-install, the bootstrap.sh script which should come in the package is helpful - it automatically downloads the required dependencies. http://hackage.haskell.org/trac/hackage/wiki/CabalInstall
Next up: Ubuntu. There's a Linux Link on the Haskell Platform Page. Ooooh, there's an Ubuntu link. Ooooh! there's even a package for Natty, great! Version 2010.1.0.0.1 WTF? Where's the 2011.2 package? There isn't one.
I see there is a 2011.2 package for the next version, but it's probably too much trouble to fix up the other dependencies.
b) On Ubuntu Natty I installed the generic linux GHC 7.0.3 binary. Downloaded Haskell Platform 2011.2.0.1 source distribution. ./configure worked happily. make fails as follows.
Building transformers-0.2.2.0 "/usr/local/haskell-platform-2011.2.0.1/bin/ghc" "--make" "Setup" "-o" "Setup" "-package" "Cabal-1.10.1.0" <command line>: cannot satisfy -package Cabal-1.10.1.0: Cabal-1.10.1.0-1fb2094e19492373b1a39284193e7984 is unusable due to missing or recursive dependencies: process-1.0.1.5-55dfaccf3a91c4cb8f6284a0bafef198
That's odd. I think 7.0.3 comes with Cabal-1.10.1.0.
