I don't know if this is relevant, but locally we had occasion to install the
g++ compiler for MacOS from fink:

    http://www.finkproject.org/

This was because there was some complication (don't recall details) in getting
the new Xcode installed on the Mac in question.

The version of g++ from fink installs as "g++-4" (to keep it orthogonal to the
one from Xcode):

  $ g++-4 --version
  g++-4 (GCC) 4.6.2

My point is that if the problem in question DOES stem from the use of an old
version of g++, it's a problem that might be relatively easy to fix.  Of
course, downloading the full Xcode stuff from Apple would also fix the
problem.
