I get the error:
"Setup.lhs:11:53
	Couldn't match expected type 'Distribution.Verbosity.Verbosity'
		Against inferred type 'IO FilePath'
	In the first argument of 'readPackageDescription', namely

	In a 'do' expression:

I have tried the darcs stable branch and getting the gziped src both
have the same issue.
I should add that this builds fine with 6.6.2, I thought I remembered
that there was some sort of change to Cabal that occurred around ghc
6.8.2 but I cannot remember what it was.
Is there a known workaround for this?
