@sergey-safarov can you please add ``[skip ci]`` to any commit message of pkg/kamailio/obs changes? anything related to pkg doesn't need to be build by travis-ci

@sergey-safarov - can you check if pkg-config has the settings for ruby-x.y, like for example: 'pkg-config --libs ruby-2.5`.

Overall, I am fine to do that change, I see that `-lobjc` is returned by pkg-config on MacOS, but this is irrelevant, as I said, that part should be used for the cases without pkg-config settings, which are the exceptions and likely they will need to be changed based on used OS.

So, you can make a separate commit for the Makefile of app_ruby and you can push it to git repo. It can be also backported.

Pushed that commit, can you test and see if now all ok? Thanks!

Let's leave it as it is for the moment. If someone complains app_ruby doesn't work for ruby 1.x, then we can change it to what you proposed. Most OSes have ruby 2.x anyhow.

@sergey-safarov - you can merge it. If @linuxmaniac want to amend, it can push a commit afterward.
