The buildbot is not able to compile p5.18-opengl and p5.20-opengl.

But it works when building from source on a regular computer. Buildbot is apparently "missing some gui initialization".

Search engines find a lot of hits with the same error message, for example

Yes, it is known that the buildslaves cannot do all the GUI things that you can do on your computer when you're logged in as a regular user. Sorry.

What I don't understand is why the build fails. Couldn't the installation proceed in such a way that one would avoid the failure?

That is: couldn't the source code be modified in such a way that it wouldn't throw an error?

This happens on my machine as well. It started three updates ago and I've been running into it for about three months and haven't been able to update my ports since that time. I'm trying to port upgrade outdated on OS X Mavericks 10.9.5 and run port selfupdate before that. Any help is greatly appreciated. Thanks.
