Curious, even after using the /Developer includes and lib for
configure, the config.log file contains the following:


PATH: /opt/local/bin
PATH: /opt/local/sbin
PATH: /usr/bin
PATH: /bin
PATH: /usr/sbin
PATH: /sbin
PATH: /usr/local/bin
PATH: /usr/X11/bin
PATH: /opt/local/bin
PATH: /usr/local/git/bin
PATH: /usr/local/mysql/bin
PATH: /usr/texbin
PATH: /usr/local/Trolltech/Qt-4.4.1/bin
PATH: /opt/local/bin
PATH: /opt/local/sbin

...(oh yea, that path has redundancy baby, but it's not intentional
:-o)  No sign there of anything in /Developer/...

So the build config is picking up all the macport perl and python installations.
