Which is what I said: subports.

I can force ImageMagick to build without OpenMP by defining a no_openmp variant in a local port repository, but that's ultimately unsatisfactory, since I'd like to use OpenMP in other parts of the program.

It sounds like a complete mess and I don't know what to think about it either.
