Yes, I now have it actually running.

Still some problems to work out, though.  For one thing, the program
crashes every time I try to subscribe to a group.  I expect, though,
that this problem will clear up once I get about the business of
converting it into a proper port and get the various make options and a
decent set of patches worked out.

Cool, I'll definitely take a look.

Yes, I've looked at the docs a bit, but need to do a lot more.  This is
my first time dealing with a port that uses this stuff, so I'm sort of
"out of my element" here.

Still, this program (klibido) is definitely worth the effort, and will
make a fine addition to FreeBSD's ports collections, once I get all the
kinks worked out.

Thanks.
