Maybe the xorg-server and libGL ports install the libglx.la etc stuff 
into a folder called share/xorg/gl-libs, and the nvidia-drivers install 
their stuff into a folder called share/nvidia-driver/gl-libs.

Further, the libGL port installs a script libexec/xorg/link-gl-libs.sh, 
which links lib/modules/extensions/libglx.la to either the stuff in 
share/xorg/gl-libs, or the stuff in share/nvidia-driver/gl-libs, 
depending upon whether share/nvidia-driver/gl-libs exists or not.

And then the libGL, xorg-server and the nvidia-driver libraries all call 
this script, both upon installation and deinstallation (via appropriate 
@exec and @unexec entries in the pkg-plist files).

The advantage of this over the libmap.conf idea is that this handles the 
static libraries as well as the dynamic libraries.

If you guys think this is a good idea, it is well within my abilities to 
produce a proof of concept PR.  What do you think?
