Build error with wip/kdebindings4-python (issue for Python < 2.5)

Hi all,

When trying to compile wip/kdebindings4-python, I encountered the
following error:

[ 98%] Built target kpythonpluginfactory_automoc

This is on NetBSD 5.0_RC1/i386, with python24-2.4.5nb2.

It seems this is due to an interaction with QT, according to this bug
report filed with the Python developers:
http://bugs.python.org/issue1086854
(In summary, this is because of name collision between QT and the
Python header file in question: QT's moc preprocessor reserves extra
words beyond what standard C++ specifies, including "slots", which
appears as a variable name in Python's object.h.  This was accounted
for in Python 2.5.)

I've confirmed that rebuilding against python25-2.5.2nb4 avoids this
problem; everything compiles and installs successfully.

So I think either the package needs to be marked as requiring Python
2.5 or above, or else there needs to be a patch to fix this issue if a
user's employing an older version of Python?

Regards,

Dave
