PyBOMBS (Python Build Overlay Managed Bundle System) is the GNU Radio install management system for resolving dependencies and pulling in out-of-tree projects.
It seems pylint is confused because AbstractYaml.__init__ may leave _dump uninitialized. In any case, 4cbdab04741e0735f0db697fd9a79a3ee1c0089e made it impossible to reach the problematic else clause in AbstractYaml.dump, so we can simply remove the whole if statement.
I also noticed that ruamel version check was broken; it requires the minor version number to be at least 15, and so it would incorrectly reject things like versions 1.0 through 1.14 (if they were to appear in the future). I simplified the check to compare against the tuple (0, 15), which should correctly compare version numbers.
