It is very easy to overload package versions locally for your needs, and it's quite easy to push that upstream to Guix so that others may benefit as well :)
Can you explain (or point to an explanation) of exactly how to do that? The Guix versions of Erlang and Elixir are way out of date, and I would like to push a fix.
See here[0] for pushing a fix, here[1] for the anatomy of a package definition (often you only need to bump the version number and update the hash, but compilers may be a bit more involved). It may be useful to define package variants[2], which is what I do for some packages locally. You can also see this page[3] for using ad-hoc package variants using command line flags. Hope this helps :)
Hm, simple version bumps tend to be outstanding for about a week for me before they are merged, and in the meantime I just add my package definition to my profile. Is there more to it than that?
