New comment by ahesford on void-packages repository https://github.com/void-linux/void-packages/pull/28996#issuecomment-784255185 Comment: Yes to adding `libevent-devel` to `makedepends`. The `ompi_monitoring_prof.so` library is not intended for linking; it is [supposed to be used with LD_PRELOAD](https://github.com/open-mpi/ompi/blob/master/ompi/mca/common/monitoring/monitoring_prof.c#L30-L33). I recommend ```bash mv "${DESTDIR}/usr/lib/ompi_monitoring_prof.so" "${DESTDIR}/usr/lib/openmpi" ``` in `post_install` to keep this library out of `/usr/lib` but make it available to those interested in profiling without requiring `openmpi-devel`.
