[Rivet] rivet and GENSER

Hi Anton,

Thus spake Anton Karneyeu (Anton.Karneyeu at cern.ch):

Sounds like a failure during the installation.

It should be. But I think you should simply wait a few days. We are
about to release Rivet 1.2.0 next week, which is a _major_ improvement
over 1.1.3.

This has long been fixed in the Rivet development version and the fix
will be in the 1.2.0 release. So if you can wait until next week ...

Have a look at the version in http://svn.hepforge.org/rivet/trunk/bin/
We are now using cElementTree if xml.etree.cElementTree is not
available. This works fine with the older Python versions on SL4/SL5.

Cheers,
