The patch for p5-BSD-Process could possibly be improved (e.g. to support process info that is available on DragonFly but not on FreeBSD), but it works well enough like that.
Thanks, these are in dports now.
A couple of them were dependencies for other ports, but they didn't succeed to build, so only these 4 ports were added.
