OK.

OK.

The background behind all this: 

Do people consider it worth to have OSG-1 and OSG-2 packages in
parallel?

The run-time environments/packages could rather easily be made
installable in parallel (e.g. by introducing a set of OSG-2 packages), 
but implementing this for the devel packages would be non-trivial.

For the moment, I've upgraded OpenSceneGraph to 2.0 on rawhide
(replacing OSG-1), ... but I could revert this.

Could you bugzilla this issue? Which data files are you referring to?
OSG's sample data sets unfortunately can't be shipped with Fedora, due
to licensing issues.
