The the ruby_prof.bundle is referring to Ruby by absolute path of what compiled it. This needs to be changed to be relative to SketchUp.

Complications because SU fully qualify frameworks with patch versions, so Ruby upgrades from 2.5.1 to 2.5.3 to 2.5.5 have Ruby located at different locations relative to the SketchUp app. Need to use @rpath. Unfortunately it's not possible to future predict this, so the binary needs to change any time SU updates the Ruby version, even patch versions.
