I think I'm getting there with it now.

core-image-weston pulls in clutter which wants cogl.

I think these two lines in cogl-1.0.inc are causing mesa to be pulled in
incorrectly, but I'm not sure what ERDEPENDS does...

# Extra RDEPENDS for PACKAGECONFIG
# This has to be explictly listed, because cogl dlopens the backends
ERDEPENDS_GL    = "libgl"
ERDEPENDS_GLES2 = "libgles2"

Alex
