To build the trunk Python 3k, it seems that Python 2 has to be installed. This is because Objects/typeslots.py is called in the Makefile, and this file uses Python 2 "print statement" syntax, which fails if $(PYTHON) is actually Python 3. This shouldn't be necessary, as typeslots.inc is also checked into subversion, and should have a newer time stamp than typeslots.inc (perhaps not currently, but that is the plan, anyway). In any case, I now made the script 2-vs-3-agnostic. Regards, Martin

I had the error pop out in a real build, so the time stamp is probably not a 100% guarantee. Therefore I think it's good that you made it version agnostic. This should be probably be a requirement for all scripts that are part of the build.

Thanks, Eli
