As I committed the transition of python25 I had to make a few drawbacks
to keep it compatible with existing py25-* ports and thus I kept the
directories in the original location. But later we discovered that this
causes problems for some ports (infamous "Not a directory" issue). The
problem appears when you have a symlink and a port then tries to use
that as a regular directory. Therefore no symlinks anymore for python26
to avoid problems.

Actually software should be asking python where it's headers are (by
using python*-config or requesting the path to
lib/python2.6/config/Makefile). The assumption of include/python* does
just not always hold true.

Yes, it's the way python wants it when being build as a framework. As a
result python based ports have to symlink any important files installed
in the python prefix (e.g. in bin/ or share/) back to the regular prefix.
