This could be a bug in gtk+3 recipe when using something else than mesa:
The wayland packageconfig depends on "virtual/mesa" when it maybe needs
"virtual-egl" instead -- what it's really looking for wayland-egl.pc (which
is normally provided by mesa but I guess on your system it's something
else).

As an aside I have to admit the definitions of our various
virtual-whatevers are not clear to me at all... Is this something we could
reasonably document better ?

Here the glamor packageconfig seems to be missing a dependency on something
that provides libgbm (again we probably don't normally notice this because
the provider is mesa). My guess is that "virtual/libgl" _usually_ provides
libgbm, so adding that to glamor packageconfig dependencies might be a fix.
