Well aware of it. Unfortunately there is no easy way to tell where the
user wants to retrieve OpenGL from on OS/X (this is because it could be
roll your own/darwin ports/macports AND it may be different on older
versions of OS/X). So you are forced into specifying it on the
./configure line.I also HIGHLY recommend going one step further and do
something like:

 LDFLAGS="-L/opt/lib"
CPPFLAGS="-I/System/Library/Frameworks/OpenGL.framework/Headers
-I/Applications/opt/include"

/opt would be whatever location you install macports to. /opt would be
the default.

The reason for Linking and includes also being specified is so that the
proper pkg-config files can be picked up.Without these lines some
libraries may not be loaded as you would expect and some functionality
may go missing.
