Yah, that's tricky.  I solved it the following way:

- install mesa
- install nvidia drivers+libs
- have /usr/pkg/lib/libGL.so point to /usr/pkg/lib/libGL.so.1.0.5, which 
should be from mesa.  It is important that this lib has the SONAME set to 
libGL.so.1 (you can check with objdump -x)

now compiling should link to the mesa lib, but then libGL.so.1 will be 
used by the runtime linker.

But looking at your compiler output, libGLU depends on libGL.so.1.0.5, 
which is bad.  You will need 
<http://chlamydia.fs.ei.tum.de/~corecode/unsorted/libtool-dragonfly.diff> 
this patch as well, I believe (and recompile Mesa+libs depending on Mesa).

Not sure whether I have submitted this to pkgsrc/upstream.  Maybe somebody 
could do that? :)
