Comment (by kuroyagi at therandomwalker.net):

 It is caused by the failure of configure to find libGL[[BR]]
 It is clear from the following config.log


 {{{
 configure:25194: checking for glXGetConfig in -lGL
 configure:25224: /usr/bin/gcc-4.0 -o conftest -O2 -I/usr/X11R6/include
 -I/opt/local/include -I/usr/X11R6/include -L/opt/local/lib conftest.c -lGL
 -lm -lXmu -lXext -lXt -lX11 -lxm -lxt -lSM -lICE -L/usr/X11R6/lib
 -lpthread  >&5
 ld: cycle in dylib re-exports with /usr/X11R6/lib/libGL.dylib
 collect2: ld returned 1 exit status
 configure:25230: $? = 1
 }}}


 The reason configure fails to link to libGL is explained at
 [http://developer.apple.com/qa/qa2007/qa1567.html]


 following patch resolves this linking problem but #14085 still exists
