I looked through this and nothing was obvious.  According to depmod, neither
mesa nor mesa-gl have any direct "reverse depends", i.e. packages that depend
on them.  As far as I can see, it's just coming from the xserver-xorg dependency
on virtual/mesa.

Which led me to another experiment which I truly do not understand.  I removed
the mesa-gl recipe and now when I try to build 'virtual/mesa' I get a message
that there is no provider :-(  However, I *can* build mesa with no problems.
I also checked it against the other PROVIDES from mesa.inc and all of them
except for virtual/mesa work.  How can this possibly be?
