I don't know why the hat package is not installed on your system.  But I
did find some packaging errors that mean, even it hat was installed, it
would not work with ghc-6.6.

Essentially, ghc now needs to know both the package name _and version_
when building the library, otherwise the linker gets confused and can't
resolve names.  I've pushed a fix to the darcs repo, and will probably
re-roll the 2.05 distribution as well.
