No, Cabal requires that things needed by Setup.*hs files (such as the FilePath module) come with all compilers. That can be done by shipping the filepath package with all compilers rather than putting the module into the base package.
When last speaking to Duncan he gave me the impression that Setup.hs can only depend on base. If this is not the case, and we have a procedure for "making this a library that comes with absolutely every compiler", then I'm happy to create it as a filepath library, provided:

"runhaskell", "ghc --make" and hugs would all work. "ghc -package base -package Cabal" wouldn't, but I doubt that will trip anyone up given it won't be in any docs (and so anyone it does trip up probably knows how to fix it anyway).
i.e. on parity with the base libraries. Does such a place/package exist?
You just have to convince each implementation separately to ship with it. Thanks Ian
