[Bug 193693] Merge mail/dspam-devel in to mail/dspam

[Danny Warren]

Hello all!

I'm the current maintainer of mail/dspam and mail/dspam-devel, and I 
need some help committing the patch found in bug #193693.

This one is a little messy as both ports have gone stale over the last 
few years, so apologies and thanks in advance to whomever jumps in to help.

I will also need some help adding an entry to MOVED once the commit is 
done, so that we can officially retire dspam-devel.

Thanks!
Danny Warren
