Hi,
It seems I've been able to mess up my ghc installation pretty badly.
Here is what happens if I just try to invoke ghci from the prompt:

I would still vote for that error in the 'worst ghc error message contest'.
I got it just last night with 6.13 when I tried to run the Setup.hs function
in base:
~/n-heptane/projects/haskell/darcs/base-3.0.3.2 $ rm Setup.o Setup.hi
