The problem is that if you install pretty, Cabal will suddenly cease working until you recompile it. It depends on a version of pretty which gets bundled with GHC is purportedly of the same version as the one on hackage, but the two aren't binary compatible. So when it tries to use it, everything goes boom.

If you compile with different flags then the results will not necessarily be binary compatible. I suspect that's what happened here. Thanks Ian
