I have a special question for Fedora Legal. voro++ license seems to be free (see full text below). However, I'm not sure what I should set in spec file for such a custom license. Are there any recommendations / guidelines on how to handle it?

FYI, here is the updated package I'm currently using for building gmsh.

Spec URL: http://smani.fedorapeople.org/review/voro++.spec
SRPM URL: http://smani.fedorapeople.org/review/voro++-0.4.6-2.fc21.src.rpm

%changelog
* Sat Jun 14 2014 Sandro Mani <manisandro> - 0.4.6-2
- Spec cleanup
- Add voro++_virtual-destructor.patch

@Alexey: Since the other reviews of the other gmsh dependencies are moving along nicely, mind if I take over this one as well?

Ok. It will be reasonable.
