Ok, I'm a bit stumped now, but there are some other things we can try.

- Can you run the hello world example from inside GHCi using your
  installed 5.04.2?  (type 'ghci Main.hs' and then 'main').

- Start up GHCi with a few packages: 'ghci -package util -package
  text' just to make sure it can find all its libraries.

- go into ghc/utils/genprimopcode in the source tree, and try to
  find out why genprimopcode is crashing.  First, do './genprimopcode
  +RTS -Sstderr' and see if you get any output.  Try gdb on it, 
  and see if you get any useful information out of that.
