We could: * leave the current patch applied to clang-* (to teach clang where to get the library if it is installed) * make clang-* no longer depend upon libomp * Add a post-install note of "to enable OpenMP support, install libomp" * Have libomp depends_build upon the latest clang on the platform (is there an automagic way to do this?)
For most (standard install; many pre-compiled binaries) users, libomp would be installed via pre-built packages, and wouldn't have to pull down clang to build it. This would also avoid having multiple libomp instances on the system, which seems like a "good thing". How does that sound? I like having 'sudo port install clang-X' yield a fully featured (-fopenmp just works) compiler, but a reminder note and simple "sudo port install libomp" isn't all bad... - Eric
