Comment(by simonmar):
unix is a dependency of directory, from `directory.cabal`:
{{{
if os(windows) {
build-depends: Win32
} else {
build-depends: unix
}
}}}
I suspect the problem has something to do with this

}
}}}
that patch itself should be fine, and it certainly works here, so
something else must be going wrong. I suspect it's one of those 32/64-bit
problems with the FFI on OS X 10.6: probably the unix package is using the
wrong offsets for `struct stat`, so that `Posix.isDirectory` isn't working
correctly.
Does that give someone enough clues to fully diagnose the problem?
