help, what's wrong?

dear sir,

I installed

rpm -i ghc-doc-5.04.2-1.i386.rpm

rpm -i ghc-5.04.2-1.i386.rpm

when i type ghci in my terminal, i get this error. (I am using redhat 9,
fluxbox windows manager.)

--------------------------------------

Loading package base ... linking ... /usr/lib/ghc-5.04.2/HSbase_cbits.o:
unknown symbol `__umoddi3'
ghc-5.04.2: panic! (the `impossible' happened, GHC version 5.04.2):
        can't load package `base'

Please report it as a compiler bug to glasgow-haskell-bugs@xxxxxxxxxxx,
or http://sourceforge.net/projects/ghc/.
