Comment:

 Replying to [ticket:40716 jcverle@…]:
 > In looking at the METIS Portfile, I noticed a some errors. First, the
 license is not correct. METIS is released under the Apache License,
 Version 2.0 (the Portfile has it listed as "Restrictive").

 Confirmed; the license field was added in r84527 at which time it had a
 more restrictive license. Fixed license in r112022.

 > Second, an openmpi variant is listed. METIS does not have an MPI
 variant; ParMETIS (which is a new port) is the MPI version of METIS. METIS
 does have support for OpenMP, though I think it requires downloading of a
 separate tarball. I have never used that capability, personally, so I
 can't speak to how it would be implemented in the Portfile.

 The openmpi variant was requested and provided in #35018 and committed in
 r94816. I don't know any more about it.

 > Finally, it appears the Portfile does not specify a compiler. I believe
 that, in that mode, CMake uses whatever compiler it finds first.

 MacPorts chooses a default compiler based on the Xcode version. Most ports
 should not override this choice. It is possible that the use of openmpi
 constitutes a valid exception to this rule but I don't know.

 > I would like to start using METIS, but I would like to have some control
 over which compiler it uses. (Admittedly, it probably does not matter in a
 big way, since METIS is straight C code, but I would at least like to know
 which compiler is being used.)

 You can find that out by running "`sudo port -s install metis`" and
 looking for the line that says "Using compiler". As of Xcode 4.2, the
 default compiler is clang. Most ports respect this setting; if a port
 doesn't, it's a bug.

 > I would be willing to help maintain this port (I made the same offer to
 the ParMETIS port), but I am a complete novice when it comes to Portfiles.
