No. I meant the order listed in the parts option.

develop eggs are not parts. They are built using whatever Python is  
used to run the buildout.

I don't see ZODB listed in your buildout.  If it is a dependency of  
one of your recipes, that would cause it to be built with your system  
Python.

That's difficult for me to believe.  I might try to reproduce your  
buildout, but I don't have the various bits it wants to build as a  
develop eggs.

Byte-compilation isn't really the issue. The issue is extensions.  if  
ZODB is a dependency of any recipes, then it will be build with  
whatever Python is used to run the buildout.

Move postgresql to the front of your parts list. Your interpreter part  
lists the psycopg2 egg. The egg recipe will download this distribution  
and try to install it.  At that point, it hasn't gotten to your  
psycopg2 part yet.
