Builds for gnuradio master using the worker Centos_7_6_py3_qt5_master fails. It looks like the reason is the

The worker seems to be using Boost version: 1.53.0 judging from the output of the cmake step.

As far as I can read on the interwebs (not linked directly as not to spam their thread with github events):

I don't think it is fair to support that old version of boost on master, so maybe we should make sure this test it not run for master?
