ghc needs memory

[John Meacham]

Yes, it appears to have been a corrupted 'hi' file. cleaning
everything out and starting
from scratch fixed it. I was seeing it on both compilers because my
two systems are
synchronized via unison so the bad file got bounced back and forth.

I have not tried using 7.2 yet, the separation of haskell98 and base
is a huge pain
for a lot of my projects, I have not decided on an appropriate
workaround yet so I
still target 7.0 and 6.12 (the releases that came with the last two
versions of ubuntu
by no coincidence)
