Comment (by ryandesign):

 It's probably exactly what Josh said above:

 Replying to [comment:1 jmroot]:
 > It's also building C++ code using `configure.cc` and seems to be
 ignoring CXXFLAGS, so it may also need the workaround used by e.g. py-re2
 in order to use the right stdlib.

 The workaround in py-re2 is to set `configure.cc` to the C++ compiler,
 which is terrible but since setuptools/distutils is terrible I don't know
 that there's a better option. py-re2, for the record, still doesn't use
 CXXFLAGS, so it too fails to build on 10.8.

 The reason why these ports are able to build on 10.7 and earlier may be
 that they use a MacPorts clang compiler on those OS versions, and unlike
 Xcode clang compilers which default to libstdc++ on 10.8 and earlier,
 MacPorts clang compilers default to libc++.
