Ben,
So it looks like the ghc libraries come installed in *.hi files. This looks to be a binary library. Is that the case? Is there a tool to see what Haskell functions and etc are in a .hi file?
GHC's *.hi files are "interface files", a product of GHC's separate compilation. foo.hi contains the information needed to compile a different module which depends on foo. So a binary library package needs to contain both the object code, and the matching interface description, which is the *.hi file. By the way, both are very sensitive to the version of GHC that compiled them. There's no attempt or claim at binary compatibility between GHC versions. The GHC user manual is a great resource: http://www.haskell.org/ghc/docs/6.8.3/html/users_guide/separate-compilation.... John
