If anyone cares to dig deeper, the dying words from configure (without the
extra arg) are
configure:4270: checking for glEnd in -lGL
configure:4295: gcc -arch x86_64 -std=gnu99 -o conftest -g -O2
-I/System/Library/Frameworks/OpenGL.framework/Headers -DHAVE_PNG_H
-I/opt/local/include/libpng14 -DDarwin -DNO_GL_PREFIX -I/usr/X11R6/include
conftest.c -lGL -framework OpenGL -dylib_file
/System/Library/Frameworks/OpenGL.framework/Versions/A/Libraries/libGL.dylib:/System/Library/Frameworks/OpenGL.framework/Versions/A/Libraries/libGL.dylib
-L/opt/local/lib -lpng14 -lX11 >&5
ld: library not found for -lGL
collect2: ld returned 1 exit status
configure:4295: $? = 1
configure: failed program was:
| /* confdefs.h */
...etc...
whereas the successful configure has
configure:4270: checking for glEnd in -lGL
configure:4295: gcc -arch x86_64 -std=gnu99 -o conftest -g -O2
-I/System/Library/Frameworks/OpenGL.framework/Headers -DHAVE_PNG_H
-I/opt/local/include/libpng14 -DDarwin -DNO_GL_PREFIX -I/usr/X11R6/include
-L/usr/X11/lib conftest.c -lGL -framework OpenGL -dylib_file
/System/Library/Frameworks/OpenGL.framework/Versions/A/Libraries/libGL.dylib:/System/Library/Frameworks/OpenGL.framework/Versions/A/Libraries/libGL.dylib
-L/opt/local/lib -lpng14 -lX11 >&5
configure:4295: $? = 0
configure:4305: result: yes
The odd bit is that configure apparently does know about OpenGl.framework and
the .dylibs inside of it; it just doesn't seem to know how to tell -lGL about
it.
