Futhermore, I’d like to add a +pythonXX variant to enable python bindings: I thought about declaring gmsh +pythonXX both in CMake and PythonXX PortGroups, but obviously they conflict in the way configure is handled.

Well the python portgroup is for making python module ports. It's not for adding +pythonXX variants to non-python ports.

If the gmsh build system allows this without too much trouble, the nicest option would be if you could create pyXX-gmsh subports which could use the python portgroup. Or a standalone py-gmsh port using the python portgroup and sharing gmsh's dist_subdir.

As for the conflict between the python and cmake portgroups, I'm guessing that's occurring because the python portgroup wants to turn off the configure phase, and the cmake portgroup wants to change the configure phase? Does simply adding "use_configure yes" work? If not, what problem are you seeing?
