Resurrecting an old thread.

I would like to find out:
  1. Has there been any update on how to workaround this?
  2. Does building 6.12 from macports (or from source on a macports enabled
system) fix the problem?

It seems like more than just GHC is affected by this, but I'm having trouble
digging up solid information on the web about how to workaround it.  Many
sources (such as stackoverflow) point to this thread so posting a solution
here would be a win.

Thanks,
Jason
