rgl uses autoconf to build its configure script, and as far as I can 
tell the current version of autoconf (one version newer than what we 
used) knows nothing about leopard.  So we need to change the 
configure.ac input in order to make the above happen automatically.

Do you (or anyone else on the list) know what the change would be?  If 
you do, a patch would be appreciated:  I don't know much at all about 
autoconf (I'm a Windows guy), and don't have a leopard system to play with.
