CVS is a little bit dumb about how it manages directories. OS X is
a little bit dumb about how it manages filename case. As people
committing to a CVS repository that gets used on case-insensitive
filesystems, it's our job to prevent these dumbnesses from interacting
badly. What you're seeing is that in a couple places, we've missed
a spot.

It's annoying that a `cvs update` makes noise even when it has
nothing to do, but that's the extent of the problem. Besides that
(and the occasional upstream developer actively opposed to dealing
with case-insensitive filesystems), pkgsrc and everything in it
works quite well on OS X.

We've missed a few similar spots before. 7 years ago today, I did
some surgery on the repository:

<http://mail-index.netbsd.org/pkgsrc-users/2007/06/15/0002.html>

To address what you're seeing, we'll need to perform some followup
surgery. To prevent another recurrence, we'll need to install a
pre-commit hook. (If the hook works well for pkgsrc, we'll probably
want it for src too.)
