A patch is attached. It looks for glibtoolize if libtoolize isn't in the 
path. The name conflict is with 'libtool' so the libtool package is 
shipped by Apple with a name prefix of 'g'. Thus, searching in this 
order is safe.

We've been doing something very similar for a while in libogg, so it's 
had some portability testing. Tested on linux and MacOS 10.3. Of course, 
we still don't build out of the box because Apple doesn't ship an 
accessible libjpeg, but should do once one is installed.

I still have cvs access, so I can commit this if you like.
