[Rivet] Check Python Version in Bootstrap

[Andy Buckley]

Hi Markus,

Thanks for the report -- I wasn't aware that that function was not
available in Python 2.6. We do want to be 2.6 compatible so I will
rewrite that for the next release. We might also add a minimal Python
version check into the bootstrap -- thanks for the suggestion.

I hope you can find a workaround for now, e.g. make a local make-plots
script using Py2.6-compatible functions. If you do that, please let us
know and we'll merge it and credit you!

Andy
