Hi,

I was installing various haskell packages from hackage.

When I was installing HaXml, I think it was complaining about Text.PrettyPrint.HughesPJ not installed or something. (can't remember the specific message and I can't reproduce now...)

So I installed "pretty-1.0.0.0" package as well.

Ever since then, when I try to install other haskell packages, I get the following error message:
"brian@bp-desktop:~/Download/mtl-1.1.0.0$ runghc Setup.hs configure
<interactive>: /usr/local/lib/ghc-6.8.2/lib/Cabal-1.2.3.0/HSCabal-1.2.3.0.o: unknown symbol `prettyzm1zi0zi0zi0_TextziPrettyPrintziHughesPJ_lvl18_closure'
ghc-6.8.2: unable to load package `Cabal-1.2.3.0'"

Does anyone know what the problem is?

Currently installed packages are:

    Cabal-1.2.3.0, HTTP-3001.0.4, HUnit-1.2.0.0, X11-1.4.1,
