No I do not.  It's in
/Library/Frameworks/Python.framework/Versions/Current/bin/
In order to get the build to work I have to put it in /usr/local/bin
(or, I'm sure
that /usr/bin would work too).  Note that I *can't* just link it; I've
got to actually
remove the Python framework copy.  (I think that's because "which xml2-config"
still returns the Python framework directory.)  Once I've removed the Python
framework copy, the build works with either that copy moved to /usr/local/bin
or the "fake" copy that you sent me in /usr/local/bin.

Thanks, I might try that later,
