(ghudson@MIT.EDU). He doesn't think this patch is particularly
beautiful, but i'm not sure much can be done about that.
in particular:
(1) installing to a different file name, then chowning that
and using 'mv' brings up a couple of bugs that
can't reasonably be tested for (and shouldn't have to be),
(2) you don't particularly want people trying to use the libraries
until they've been successfully installed, anyway.
