It also needs someone with good knowledge of MacPorts which you may have.

The error does not happen in Python code (though it may be triggered
by something from earlier on in the compilation process) unless there
is Python code being executed during port activation. Marcus wrote
that the error also appears for him if compiling with Python 2.4 which
means the problem is not specific to Python 2.5 either.

Let's assume for a moment that "Not a directory" errors from different
ports (with Python bindings generated by SWIG) are caused by the same
problem. If so, we can use a fragment of a detailed error log from
http://lists.macosforge.org/pipermail/macports-users/2008-July/010888.html
(below). I can not say more w/o detailed knowledge of port activation
process, but it looks like the error happens at the very end when
files are being added to the file_map.

Perhaps the problem is related to the directory layout of how Python
(python24, python25) is installed by MacPorts?
