We are getting a lots of packages inside the devel:languages:erlang. We should think to change project structure to avoid massive rebuild of packages at erlang updates. My suggestion is to follow devel:langages:python approach: maintaince project for erlang is devel:languages:erlang:Factory, and packages inside devel:languages:erlang are built against erlang from the *distribution* repository (or from openSUSE:Factory for factory).
Since we can not just broke the things, the following roadmap is proposed:
1) move devel:languages:erlang/erlang to devel:languages:erlang:Factory/erlang and make a link from devel:languages:erlang:Factory/erlang to devel:languages:erlang/erlang. Change devel project for openSUSE:Factory/erlang to devel:languages:erlang:Factory.
2) disable devel:languages:erlang/erlang for Factory and upcoming openSUSE 13.1 in order to make erlang packages use erlang from the distribution. then disable for 13.2, 13.3, etc. At this step for openSUSE >= 13.1 packages from the project will use erlang from distribution, and the packages for openSUSE < 13.1 will use erlang from devel:languages:erlang, as they do now.
3) when all versions up to 12.3 will be discontinued, drop disabled devel:languages:erlang/erlang finally.
