Port names are not keywords...

Might be another dreaded C++11 problem - but this time stemming from libunwind-headers?

10.6 also affected.

hmmm. I didn't try building it on Leopard Intel, tho. For a start, I'd try building it with clang-3.7 or newer instead of gcc-4.2 and see how that works for you.
