<p>It seems that some OpenGL headers are missing. Even though the builds appear to be green, the pharo.cog.spur builds terminate early because the B3DAcceleratorPlugin can't be built due to those missing headers. I'm still investigating the details but at least <code>libglu1-mesa-dev</code> has to be installed. It's possible that the build cache / third-party cache has been hiding this problem for quite some time and a recent change to the source of the plugin has caused recompilation.<br>
The effect of the termination is that not all libraries have been installed before packaging.</p>
