Comment (by snhirsch):

 Blast...  I don't really know much about the Macports build system, nor do
 I understand the failure mode.  Based on my original log, can you give me
 a quick hand-waving explanation of what's going astray and where?  Also,
 what is 'clang'?  Not familiar with that term.

 Disclaimer:  I am a reasonably experienced C/C++ coder in the Linux
 environment, but know next to nothing about the Mac OS X system (besides
 its lamentable lack of support for Valgrind, but that's a different
 story).
