Build failures on Mac OS X 10.5

I can only offer to make a rebuild with any options that might help. May
it be a problem with the GMP framework? The one for downloading
(gmp-4.2.1) might be different from the one that's globally installed
here (gmp-4.2).

Probably unrelated: I had a seqfault when I tried to use my ppc ghc to
compile on intel mac using "-arch pcc" (1) for gcc, assembler and
linker. (It seqfaulted rather late in the middle of our big project --
40 MB binary -- and only after switching on optimization.)
