Comment:

 Looks like the error is:

 {{{
 configure:22945: checking for X
 configure:23169: result: disabled
 configure:24261: error: X development libraries not found
 }}}

 Looks like the port's +quartz variant not only enables quartz support, but
 also disables X11 support, but gtkglext apparently requires X11.

 You can work around the problem for now by not attempting to use the
 +quartz variant.
