Comment(by ryandesign@…):

 Replying to [comment:5 Peter_Dyballa@…]:
 > Is it possible to change the Portfile in a way that a different
 compiler, gcc-4.2, gets used?

 Yes, it is possible to do that. But if clang or llvm-gcc-4.2 can be made
 to work, we would prefer to do that.

 > I tried to compile GNU Emacs 24.0.50 with LLVM GCC 4.2 (CFLAGS="-g -H
 -pipe -fPIC -fno-common -fomit-frame-pointer -m64 -mtune=core2
 -march=core2 -Os -ftree-vectorize" LDFLAGS="-Wl,-dead_strip_dylibs
 -Wl,-bind_at_load -Wl,-t" CC=llvm-gcc-4.2 LD=llvm-gcc-4.2 CPP=llvm-cpp-4.2
 CXX=llvm-g++-4.2) and it creates a temacs which crashes when invoked to
 dump the real emacs (Segmentation fault).

 Ok. Not sure it's relevant to this ticket about cairo though.
