Hi!

Mesa needs to be configured with --enable-texture-float (especially
graphics/dri) to unlock OpenGL versions beyond 2.1. This option enables
a patent-encumbered code.

We're discussing what to do with this option.

In the meantime, you can add the following line to graphics/dri/Makefile
(after the inclusion of bsd.mesalib.mk):
CONFIGURE_ARGS+=--enable-texture-float

And rebuild graphics/dri.
