[Haskell-beginners] Uninstall GHC binary package? ()

Dear All,

After I installed the ghc binary package
(ghc-6.12.1-i386-unknown-linux.tar.bz2) manually, I can't find a way to
uninstall it. Could anyone help me out?

Thanks in advance.


I have installed two versions of ghc. One is with the ghc-6.12.1 package,
and the other is ghc-6.8.2 package. The former is downloaded to be installed
manually, but the latter is done automatically by using APT tool. They are
installed in a different way. I mean the ghc-6.12.1 is under /usr/local/bin,
but ghc-6.8.2 is under /usr/bin. (Of course, you can change this default
setting though)

My original purpose is to install the newest QuickCheck package. Having both
ghc packages seems to cause a conflict. After I try with $ runhaskell
Setup.lhs configure, I met a dependency error requiring me to install mtl
(monad transformer library). I did install by APT tool. But the retrial with
$ runhaskell Setup.lhs configure does not work because the configuration is
being done by ghc-6.12.1 package. The ghc-6.12.1 package doesn't recognize
the presence of mtl package that I installed just before. Only the ghc-6.8.2
package seems to recognize the presence of mtl package. The mtl package
seems to be built aligned with ghc-6.8.2 package. I guess this strange
phenomena comes from the different configuration of the two versions.

This is the reason why I try to uninstall ghc-6.12.1, but it doesn't seem to
provide any way to be uninstalled, unfortunately. If I am wrong, please
correct me.
