You're correct.  I missed this in my initial analysis because I linked
against a dynamic libpython that pulled in libutil automatically.  My
initial attempt broke configurations where a static libpython is used
(requiring libutil to be specified explicitly).

.. or on Solaris, where it doesn't exist.

The end result of the fix is that PYTHON_EMBEDDED_LIBS includes
python, dl and util on all UNIX platforms except Solaris, where util
is excluded, and OSX, where the entire list is kept blank (not sure
why, I just preserved the existing behavior).
