Comment(by gwright@…):

 OK, this is indeed a cabal problem.  GHC includes a copy of the libffi
 source, from which it builds an archive (libffi.a) this should be
 statically linked to the binaries produced at the end of the build.
 However, if another libffi is present (e.g., /opt/local/lib/libffi.dylib),
 it seems to get linked in first.

 Can be fixed, but not pretty.
