Update

The update from mesa 17.0.3 to 17.0.4 merged libGL, libEGL, libglesv2, libglapi, and gbm into mesa-libs, and moved dri to mesa-dri. I performed the update using portmaster, forcibly deleting old packages where necessary. But I didn’t keep a record of that.

Fixing the dependencies

After the update, running pkg check -n -d revealed:

cairo has a missing dependency: libGL
cairo has a missing dependency: libEGL
firefox has a missing dependency: libGL
freeglut has a missing dependency: libGL
libGLU has a missing dependency: libGL
libepoxy has a missing dependency: libglesv2
libepoxy has a missing dependency: libEGL
mupdf has a missing dependency: libGL
qt5-gui has a missing dependency: libGL
qt5-gui has a missing dependency: libEGL
xf86-video-ati has a missing dependency: libGL
xorg-server has a missing dependency: libGL
xorg-server has a missing dependency: gbm
xorg-server has a missing dependency: dri

Using pkg set fixed most of that.

pkg set -n libGL:mesa-libs
pkg set -n dri:mesa-dri
pkg set -n libglapi:mesa-libs
pkg set -n libglesv2:mesa-libs

The dependencies on libEGL and gbm could not be updated in this way, because it would lead to double dependencies for some ports.

So the following problems remained:

cairo has a missing dependency: libEGL
libepoxy has a missing dependency: libEGL
qt5-gui has a missing dependency: libEGL
xorg-server has a missing dependency: gbm

To solve this, I re-build the affected ports.

portmaster graphics/cairo x11-toolkits/qt5-gui graphics/libepoxy x11-servers/xorg-server

This fixed the remaining missing dependencies.
