[Haskell-cafe] haskell package installation problem

[Brian Park]

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 at 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:
=========
/usr/local/lib/ghc-6.8.2/package.conf:
    Cabal-1.2.3.0, HTTP-3001.0.4, HUnit-1.2.0.0, X11-1.4.1,
    array-0.1.0.0, base-3.0.1.0, bytestring-0.9.0.1,
    containers-0.1.0.1, directory-1.0.0.0, filepath-1.1.0.0,
    (ghc-6.8.2), haskell98-1.0.1.0, hpc-0.5.0.0, hxt-7.4, mtl-1.1.0.0,
    network-2.1.0.0, old-locale-1.0.0.0, old-time-1.0.0.0,
    packedstring-0.1.0.0, parsec-2.1.0.0, polyparse-1.1,
    pretty-1.0.0.0, process-1.0.0.0, random-1.0.0.0, readline-1.0.1.0,
    rts-1.0, template-haskell-2.2.0.0, unix-2.3.0.0, xmonad-0.5,

=========


Thank you,
