Well, you've chosen a complex topic on which to dive into it :-)

As best I can tell the pointyhat scripts use packages as prerequisites
for every port that gets built.  (Otherwise, the amount of time required
for the builds would be vastly increased).  My guess is that the default
package of py-imaging maps to py24-imaging rather than py23-imaging.
Let's see if that's correct ....

Here is a graphical map of the dependencies as seen by a system that has
Python 2.4 installed on it:

http://portsmon.FreeBSD.org/portdependencytree.py?category=www&portname=zope-cmfphoto

So www/zope-cmfphoto depends on lang/python23 and graphics/py-imaging;
but graphics/py-imaging depends on lang/python (2.4), which would, when
compiled in a clean system, indeed produce package py24-imaging, not
py23-imaging.

So this may be more a problem with the framework, not with pointyhat
(e.g. the fact that you can only depend on a port, not a specific package
of it).

My guess would be that we need to mark these as NO_PACKAGE as a workaround
until Zope can fix their code to not rely on 2.3, as some of these other
ports have done.

See http://www.freebsd.org/cgi/cvsweb.cgi/ports/Tools/portbuild/scripts/buildscript ,
but be warned that the scripts are very dense and will not quickly provide
you any answers.
