Comment(by morpheus+macports@…):

 It seems that the port was broken on Snow Leopard + Xcode 4.0.2 by r80732.
 The check for llvm-gcc-4.2 per-se is right: one of the tests hangs when
 gmp is built with llvm-gcc-4.2, but on the other hand clang seems to
 produce even more invalid code (which doesn't even link).

 I switched to gcc-4.2 and gmp builds and passes the testsuite, but I don't
 know if this would break other ports.
