[Haskell-cafe] Hint & Cabal Install weirdness.

I'm attempting to install hint, I started by doing:
cabal install hint

and it gives me the following error:

cabal: dependencies conflict: ghc-6.10.1 requires process == however
process- was excluded because ghc-6.10.1 requires process ==

So I decided to try installing it via darcs, expecting to either have it 
work, or boil it down to one or two dependencies that were causing the 
problem, my hunch was right, it boils down to the ghc-mtl package, 
leading to the same error as above. My question is, how can I fix this? 
Doing a ghc-pkg hide on either process package breaks Cabal and Haddock 
(among others) according to the error message, and even after that 
happens, cabal complains about needing ghc >= 6.6 (or 6.8, depending on 
which package I disable), even though I have ghc 6.10.

Detailed system info follows, help me haskell-cafe-kenobi(s), you're 
(all) my only hope(s)!


Arch Linux: uname -a gives:
Linux Erdos 2.6.28-ARCH #1 SMP PREEMPT Mon Feb 2 22:22:59 UTC 2009 i686 
Intel(R) Celeron(R) CPU 3.06GHz GenuineIntel GNU/Linux

ghc --version gives:
The Glorious Glasgow Haskell Compilation System, version 6.10.1

cabal --version:
cabal-install version 0.6.0
using version of the Cabal library

Thanks again,
