Updated specfile: http://dmalcolm.fedorapeople.org/python3.spec
Updated SRPM: http://dmalcolm.fedorapeople.org/python3-3.1.1-9.fc11.src.rpm
Diff between 3.1.1-8 and 3.1.1-9:
http://dmalcolm.fedorapeople.org/python3-from-3.1.1-8-to-3.1.1-9.diff

I've tested this with a sample specfile and it works.

One possible drawback is that the macro files are read (with rpmInitMacros) and
expanded on every rpm operation, which means that when python3-devel is
installed, every "rpm" invocation is going to be quietly invoking
/usr/bin/python3 twice on startup.  None of the existing macro files seem to
invoke subprocess during expansion.

Having said that, it only affects systems with python-devel installed, so I
don't see this as a problem.

I'll look at doing something similar for the main "python-devel" package.

rpmlint output is as before (see comment #38)
