You could try building g95 with llvm-gcc-4.2 instead of the default clang: 

sudo port clean g95
sudo port install g95 configure.compiler=llvm-gcc-4.2

Replying to ryandesign@…:

You could try building g95 with llvm-gcc-4.2 instead of the default clang: 

sudo port clean g95
sudo port install g95 configure.compiler=llvm-gcc-4.2

I confirm that using the above workaround the build completes successfully.
