Comment (by afb at macports.org):

 It seems that those python ports are expecting $CC to be set in build as
 well as in configure, and fall back to random values such as "" or "cc" or
 "/usr/bin/gcc-4.0" when it isn't. This probably also explains why
 rerunning the build sometimes succeeds, if something else was adding a $CC
 to the environment that can be picked up as a lucky guess second time.

 Supposedly base wants to be enhanced to support CC in non-configure builds
 ?

 Workaround meanwhile is adding `build.env="CC=gcc"` while building the
 port.
