libgms' temporary cache doesn't exist

[geofft]

libgms 9.4.24-0debathena4 applied a local patch to move the cache from /usr/tmp to /var/cache/debathena-libgms/messages; this was then merged upstream and changed to /var/cache/libgms/messages. However, I'm not seeing anything that's causing that directory to exist. Should it?

Once we figure out what's going on there, I'd also like to figure out

• if the logic for putting a temporary message there is secure (I think I trust the people who wrote it, but the general concept scares me)
• whether we should patch get_message's manpage

Oh wait, the .install file creates /var/cache/debathena-libgms. That should probably be fixed...

Fixed in r25181 and r25182.

Also r25183. However, this continues to do chmod a=rw on the directory.

I've lost state on this -- what is the status?

Looks like Geoff ack'd Alex's commits but didn't build, and Jon's mail from 12 July asking whether there was any reason to not build it went unanswered.
I don't see any reason not to go forward with it, other than zulu's continuing unhappiness.
