Thanks for the ideas, I see where you are going. Here's what I have found:
For 1, above, grep indicates that gluBeginCurve is present in libGLU.so
For 2, above, I get:

[rich at Moab lib]$ ldd libGLU.so
         libGL.so.1 => /usr/X11R6/lib/libGL.so.1 (0x4009c000)
         libc.so.6 => /lib/i686/libc.so.6 (0x4011b000)
         libpthread.so.0 => /lib/i686/libpthread.so.0 (0x4023b000)
         libXext.so.6 => /usr/X11R6/lib/libXext.so.6 (0x4024f000)
         libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x4025f000)
         libdl.so.2 => /lib/libdl.so.2 (0x4032a000)
         /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x80000000)

My original lib directive was:
         --with-opengl-libs='/usr/lib /usr/X11R6/lib'
So I added /lib/i686 and /lib, but unfortunately, I am getting exactly the 
same error:
         checking for location of OpenGL library...
         checking for glBegin in -lGL... yes
         checking for gluBeginCurve in -lGLU... no
         configure: error: *** Unable to locate GLU library.

Any other suggestions?

Thanks,
Rich
