It's a known problem. This was reported to me a couple of weeks ago.
I supply the fix Ari Suutari sent me. It will be fixed in next
release of mopd. I have a machine that has FreeBSD installed, but I havn't
benn running it since last summer when I added the support for FreeBSD.

	Yeah, I remember something like being discussed 
	a long time ago now. I'll include diffs to put.c
	in this mail in case you have time to put them
