Red Hat 8.0 omits playmidi
Red Hat 8.0 failed to include playmidi because of an issue with the HZ value varying across compatible x86 platforms (causing 6x faster playback on x86-64 for example). They never gave me a bug report but instead just silently omitted it. If playmidi is compiled with the same kernel includes as the currently executing kernel, it should not suffer from this problem. I plan to release a dynamic HZ adjustment fix in a few weeks.
