[Rivet] Check Python Version in Bootstrap

[Markus Radziej]

Hi Frank,

I have actually coded a fix that works with python 2.5. I gave it to Andy to have a look at, so we might get a permanent fix and compatability for python 2.6.

After all I am doing my EPR work with Rivet, so I actually want a version that works flawlessly on my lxcluster. ;)

Cheers,
Markus

</div>Hi all,

actually for that issue I have recently committed a fix/workaround to
the repository:
https://rivet.hepforge.org/trac/changeset/a8c29394d2ba9f1c1ca8b6f71f06f976351e1e38/

Until the next release you could patch your make-plots file accordingly.

Cheers,
Frank
