I believe I got it when I installed the Enthought Python distribution.  The
libraries are in /usr/local/lib and the header in /usr/local/include.

Yes, that worked fine.  I did actually have an xml2-config file on my
path, by the way, in:
/Library/Frameworks/Python.framework/Versions/Current/bin/

It only seems to work when it's in one of the /usr sub-directories.

Well, that didn't work either.  I get the following:
checking for C compiler default output file name...
configure: error: C compiler cannot create executables
See `config.log' for more details.

This is not a huge deal to me, though.

Thanks a lot Tamas,
