There was also something I read once (IIRC) about how some systems had
/usr which was read-only (from tape, or some other boot medium) and
/usr/local was to install other software. Since none of the GNU apps
would have been part of the vendor's packaging, they still default to
/usr/local.

I have my audio stuff in /opt/sound for some reason that I've since
forgotten. The only trouble I find is that several tarballs, even though
they read jack.pc, still insist on forgetting to look in
/opt/sound/include for jack headers. OTOH, when I changed distros about
a year ago, I didn't have to reinstall all the audio stuff - it was just
a straight copy. Reinstallation of the audio software, being in serious
flux & cvs, would have been non-trivial.

Seems like most distros like to put everything in /usr though. And if
your distro provides you with easy install mechanisms that are as close
enough to the cutting edge as you'd like to be, no harm leaving them
there.
