Comment (by simonmar):

 Replying to [comment:3 simonpj]:
 > I would love to remove this dependency. Having it implies that GHC
 depends on heavy-duty Cabal functionality, but of course it doesn't at
 all. It means that we have to compile all 60+ modules of Cabal before even
 starting on GHC.  It seems wrong.

 wanting to be encouraging.

 Removing the Cabal dep is good of course, but I just wanted to reply to
 the above - the GHC ''build system'' will still depend on Cabal, because
 we really do use Cabal to help build the libraries that come with GHC (not
 to do the actual building, but to understand the .cabal files).  So those
 60+ modules that we have to build right off the bat will stick around, and
 we'll still need a full Cabal in the source tree.

 Perhaps it's possible to extract another subset of Cabal that we use in
 the build system, but that's clearly less important than extracting the
 bit that GHC itself depends on.
