Thanks Ned.  I got sidetracked for a while but I got back to this now,
and I found my problem.

The makefile I was using to control the build on Linux was stripping the
python executable to make it smaller.

However, stripping the python executable on MacOSX breaks it completely
so it can't load its shared libraries and I get errors as in my original
message.  If I remove the "strip" operation, then everything starts to
work as expected.
