ghci on RedHat 9

I've just installed a new system w/ RedHat 9, including
patches.  Now, ghci (5.04.3) doesn't work.

First I tried the RH8 rpms available from
http://www.haskell.org/ghc.  Error.  The compiler itself
seemed fine, so then I tried building ghci and the entire
5.04.3 from source using the RH8 rpm 5.04.3 compiler.

It built, but ghci still gives an error:

Just thought I'd report it.  I was thinking about perhaps getting an earlier
compiler, say 4.08.2, and rebuild 5.04.3 but I don't know if it would help.

Thanks for all the great work!
