Error: org.macports.build for port py27-protobuf returned: command execution failed

The error appears to occur trying to download a missing dependency on 'google-apputils'. This actually builds correctly on my machine but only because the port was able to download the missing dependency. Perhaps there is a download restriction on this buildbot that is causing the download failure.

At any rate, it looks like it might be better to just supply the missing dependency. Or maybe I'm reading this wrong.

This error blocks the build of MyPaint and MyPaint-devel, which in turn blocks gimp2-devel, gimp3-devel.

Full buildbot log file is ​here.

This may be the same issue as #50282 but there's not enough information there to tell.

Build dependencies updated to depend on py-google-apputils in r145529, maintainer timeout.
