ghci of RPM package of ghc 6.2.2 segfaults

I installed the ghc 6.2.2 RPM package on a system that didn't have
anything Haskell like installed on it before. When I run ghci I get:

~/current/sources/analyzer:$ ghci
   ___         ___ _
  / _ \ /\  /\/ __(_)
 / /_\// /_/ / /  | |      GHC Interactive, version 6.2.2, for Haskell
98.
/ /_\\/ __  / /___| |      http://www.haskell.org/ghc/
\____/\/ /_/\____/|_|      Type :? for help.
 
Loading package base ... linking ... done.
Segmentation fault
~/current/sources/analyzer:$

I don't know what is going on and I don't know how to narrow it down.
Saying ghci -v doesn't help either, the last lines are:

Hsc static flags: -static
*** Parser:
*** Desugar:
*** Simplify:
*** CorePrep:
*** ByteCodeGen:
Loading package base ... linking ... done.
Segmentation fault
~/current/sources/analyzer:$

The PATH is fine, ldd says:
~/current/sources/analyzer:$ ldd /usr/lib/ghc-6.2.2/ghc-6.2.2
        libreadline.so.4 => /usr/lib/libreadline.so.4 (0x0091e000)
        libncurses.so.5 => /usr/lib/libncurses.so.5 (0x0731a000)
        libdl.so.2 => /lib/libdl.so.2 (0x00262000)

        /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x00107000)
~/current/sources/analyzer:$

How can I track this down? Has anybody experienced a similar problem? Am
I just stupid?

Any help appreciated,
Axel.
