Or, if the problem is just “not consistent across all installations” (as
opposed to 2to3 not working well for us at all):

 4- run 2to3 ourselves (using whichever version and extensions we
    consider best), and distribute the output.

IIRC, we already distribute tarballs with .c files that we have
generated from our .pyx source.  This doesn't strike me as much
different.
