It looks like the build finds the gtk and gtkgkext libraries, but not 
those for glx (and the final error message is wrong and confusing).

GLX is GL libraries for X but as far as I can read, MacOS High Sierra 
use Wayland (an aspiring replacement for X) for graphics. Probably the 
problem is there, for your build and for those trying to use the old 
binary packages as well. The article at 
http://www.tarnyko.net/en/?q=node/41 , for instance, summarize the 
issue.

For your build, looking at the brew packages list (but I don't have a 
Mac to check), maybe installing the glew package would help. Or, looking 
at it from the other side, changing gnubg's 3d code to support GL 
natively on Wayland instead.

For the old packages, maybe there is some optional compatibility layer, 
on merely some settings, available on High Sierra and needed to allow 
X applications to display on its Wayland server ?
