With the current master (Poky ffb440c37c), I can't build anything

Presumably you want just mesa-gl?
I guess your distro is setting a preferred provider for
virtual/something to mesa-gl, and something else is pulling in mesa,
probably through a default. Can you check that all of the
mesa-related virtual/* lines are set in your distro, my hunch is that
you don't have virtual/mesa set to mesa-gl.
I also compared all of the PREFERRED_PROVIDERs between my build and a stock
poky build and they are identical.
If the distro looks right then try using depexp to see what is pulling
in mesa when it shouldn't be?
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?
To be clear, 'bitbake virtual/libgl' (or any of its friends except virtual/mesa)
will cause 'mesa' to be built, but 'bitbake virtual/mesa' fails.
I found the cause :-) In addition to OE-core, I am using meta-ti on an OMAP3
target.
In meta-ti, there is this line:
meta-ti/recipes-graphics/mesa/mesa-omap3-common.inc:PROVIDES_omap3 =
"virtual/libgl"
I added virtual/mesa to this list and it now builds again. I'm not sure that
this is
100% correct though.
