[Haskell-cafe] haskell package installation problem

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-" package as well.

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

Does anyone know what the problem is?

Currently installed packages are:
    Cabal-, HTTP-3001.0.4, HUnit-, X11-1.4.1,
    array-, base-, bytestring-,
    containers-, directory-, filepath-,
    (ghc-6.8.2), haskell98-, hpc-, hxt-7.4, mtl-,
    network-, old-locale-, old-time-,
    packedstring-, parsec-, polyparse-1.1,
    pretty-, process-, random-, readline-,
    rts-1.0, template-haskell-, unix-, xmonad-0.5,

Thank you,

- Brian
