We support multiple clang versions that can be uinstalled concurrently. If
you want to use this version as clang then you want "port select":
sudo port select --set clang mp-clang-3.4
(use "port select --list clang" to see what versions are available)
I assumed the compiler would be clang-mp-3.4 but when I attempted to

Because the compiler itself produces assembly language, and the only way it
knows how to run an assembler on your system to convert that to object code
is via Apple's gcc. But it sounds like it's using it incorrectly, or you
have a "gcc" installed somewhere that does not support Apple's additions.
