I cannot see any reason to justify using pkg-config to find the OpenGL frameworks, just as it's obvious that it should be used to find the GLX library when building the XCB plugin.

This is the bug report I previously filed on this:


It's definitely a problem caused by pkg-config if your pkg-config is set 
to search your X11 installation by default (using PKG_CONFIG_LIBDIR at 
least can override the default). A conditional that *doesn't* use 
pkg-config to find OpenGL on Cocoa would be very nice.
