Thanks.

I have libGL.so (and family) in the following locations:
/usr/lib/debug/libGL.so.1
/usr/lib/debug/libGL.so.1.2
/usr/lib/libGL.so
/usr/lib/libGL.so.1
/usr/lib/libGL.so.1.0.7174
/usr/lib/nvidia/libGL.so.1.2.xlibmesa
/usr/lib/nvidia/libGL.so.1.xlibmesa
/usr/local/FWTools-linux-0.9.5/lib/Mesa/libGL.so
/usr/local/FWTools-linux-0.9.5/lib/Mesa/libGL.so.1
/usr/local/FWTools-linux-0.9.5/lib/Mesa/libGL.so.1.2.030402
/usr/local/openev/lib/Mesa/libGL.so
/usr/local/openev/lib/Mesa/libGL.so.1
/usr/local/openev/lib/Mesa/libGL.so.1.4.050002
/usr/local/openevsrc/Linux/lib/Mesa/libGL.so
/usr/local/openevsrc/Linux/lib/Mesa/libGL.so.1
/usr/local/openevsrc/Linux/lib/Mesa/libGL.so.1.4.050002
/usr/X11R6/lib/debug/libGL.so.1
/usr/X11R6/lib/debug/libGL.so.1.2
/usr/X11R6/lib/libGL.so
/usr/X11R6/lib/nvidia/libGL.so.1.2.xlibmesa
/usr/X11R6/lib/nvidia/libGL.so.1.xlibmesa

Now if I run ldd on either the libGL.so in /usr/X11R6/lib or /usr/lib I get the following.
> ldd /usr/lib/libGL.so
ldd: /usr/lib/libGL.so: No such file or directory

But if I run ldd on libGL.so.1 I get the following:
> ldd /usr/lib/libGL.so.1
                libGLcore.so.1 => /usr/lib/libGLcore.so.1 (0xb7821000)
        libnvidia-tls.so.1 => /usr/lib/tls/libnvidia-tls.so.1 (0xb781f000)
        libm.so.6 => /lib/tls/libm.so.6 (0xb77fc000)
        libXext.so.6 => /usr/X11R6/lib/libXext.so.6 (0xb77ef000)
        libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0xb772a000)
        libdl.so.2 => /lib/tls/libdl.so.2 (0xb7727000)
        libc.so.6 => /lib/tls/libc.so.6 (0xb75f2000)
        /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x80000000)

I've got an nvidia card. Does this affect my library setup such that I can't compile NVIZ properly? I found a binary version of GRASS 6.0 today and that works fine. So I guess I don't really need to resolve the compile issue, but I'm curious and would like to figure out why it didn't work, as I had problems with compiling NVIZ in the past with earlier versions of GRASS.
