>Description:
        All OpenGL packages depend on MesaLib. This causes the sytem to use
        MesaLib instead of X11's libGL, which is accelerated and much faster.
        This is caused by the searchorder for libraries:
        /usr/pkg/lib is before /usr/X11R6/lib.
        This is correct, but a problem if you want to use X11's libGL.

>How-To-Repeat:
        Just build and ldd a program that uses OpenGL.
>Fix:
        I built a meta-pkg to select the OpenGL framework that should be used.
        This way, MesaLib isn't even built if you don't need it and the
        framework you want to use is linked into /usr/pkg/lib.

        I already posted this to tech-pkg and I was told to also send a pr:
