Comment (by nad@…):

 As a followup, with access once again to 10.7, I was able to confirm that
 the build failure is seen on a plain, non-MacPorts source build of Python
 3.4.0 when using Apple llvm-gcc:


 {{{
 ./configure CC=/usr/bin/llvm-gcc-4.2 && make
 ...
   File "<frozen importlib._bootstrap>", line 672, in _code_to_bytecode
 ValueError: unmarshallable object
 make: *** [pybuilddir.txt] Segmentation fault: 11
 }}}

 and builds correctly and tests pass as expected with clang (both from the
 most recent Xcode 4 for 10.7) :


 {{{
 ./configure CC=/usr/bin/clang && make
