Because Mesa was needed for OpenGL support before XFree version 4.2.0-rX
>From ebuild 4.1.0
#We're no longer including libGLU from here.  Packaged separately, from
separate sources.

OpenGL was an option at that time.

XFree use/is based on the Mesa 3.4.2:
#  Mesa updated to the post-3.4.2 3.4 branch version as of November
2001.

The lates Mesa is 4.0.2 but the ebuild is not 'up to date' missing
support for 'opengl-update' and it shall work with al

To make the ebiuld for Mesa-4.0.[12] you need to support 'opengl-update'
see /usr/portage/x11-base/xfree/files/4.2.0-r9/opengl-update 
, /usr/portage/x11-base/xfree/xfree-4.2.0-r9.ebuild 
and /usr/portage/media-video/nvidia-glx/nvidia-glx-1.0.2880.ebuild

And you may need to relink all programs/libs that use opengl if you get
MesaOS support included.
