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

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

Thomas,
I also thought haddock should be an easy build, but it just won't do it.
  /home2/<user>/garden/haddock-0.8> runhaskell ./Setup.lhs install
  Installing: --prefix=~/cabal/lib/haddock-0.8/ghc-6.4 &
--prefix=~/cabal/bin haddock-0.8...
Then it stopped and nothing got done. (I even checked rc=0 but the
lib/bin dir does not have trace of haddock!)

I don't think haddock "has" to depend on lamdbabot. But I saw "Skipping
HaddockHoogle" during the build. Isn't the Hoogle thing related to
Lambdabot? Or they are unrelated.

Again being new to the Haskell world (only a few months), I am not an
expert on what depends on what. It would be nice to have a "type system"
to check the dependency of the many packages. Perl CPAN does a good job
on this.

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

	




Hi,
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?

Thanks,
Steve
