[Haskell-cafe] How to thoroughly clean up Haskell stuff on linux

not trying to start a flame war here, but I had pretty good success with 
apt-get and ubuntu.

however, I admit I never really got lambdabot to work.

if you install from source you can have 6.6, 6.6.1 and 6.4 all installed 
at the same time.

you just need to create simlinks for the old versions. (nothing gets 
overwritten except the symlink in /usr/bin)

are you certain haddock depends on lambdabot? that seems very strange to

[Haskell-cafe] How to thoroughly clean up Haskell stuff on linux

I have been hacking the Haskell installation a few days on Redhat Linux.
  GHC 6.6 -> 6.6.1 -> Lambdabot does not work.
  Downgrade to GHC 6.4 -> Still not working, tried cabal-install to
simplify my life, but no luck.
  Then install Cabal, Haddock -> Haddock cannot install bc Lambdabot is
not there. (And some dependency issues.)
  Remove .ghci, Haddock still not work.

It seems the Haskell world (outside the beautiful GHC) is in a recursive
non-functional blackhole.

Anyway, now my question is, how do I thoroughly clean up Haskell? (And
maybe try again after a few days of rest.)

My environment is Redhat Linux, install most stuff on
/home/<user>/<product>/ where <product> = GHC, Lambdabot, cabal,
haddock, etc. It seems there are some hidden files/dirs, .GHC, .ghci,
anything else?
