There is already an idiom with other packages (pygtk etc.) that
suggests syntax like
try:
python.require('3.1')
except:
print('Some warning about version incompatibility')
exit(1)
This concern seems better addressed within the language itself, rather
than in the shebang (which would make the decision depend on the shell
and the packaging involved).
