trouble running GHCi 6.4 on PowerPC GNU/Linux

Hello-

I am having a bit of trouble running GHCi on my GNU/Linux  
distribution and was
referred to this mail address by the crash message:

[begin terminal session-
$> ghci

$>
-end terminal session]

I am running Kubuntu 5.10 ("Breezy Badger") with kernel Linux  
2.6.12-9-powerpc
on a 400mhz iBook. I am not sure what other information would help  
you in
diagnosing the problem, but I am, of course, happy to provide  
anything else that
would be helpful.

//cheers
