That's not a catch 22.  You simply run a 2.x setup.py with options 
that cause the conversion to take place before running 3.x over the 
converted result.  Now you have a 3.x version.

Heck, you could probably just make a '2to3' command plugin, that 
converts the program and then runs python3 on the converted setup.py, 
passing in its remaining arguments, such that e.g.:

    python setup.py 2to3 [options] test ...

Would be the equivalent of running 2to3 with the specified options, 
then running "python3 setup.py test ..." in the target directory.

Again, I'm not seeing where any problem exists here.
