I tried to find some time recently to continue learning about Erlang. rebar3 seems to be the most used dependency manager, however it is not packaged in Gentoo.
I wrote an ebuild, but could not get it accepted in the official portage tree. So I created my own Gentoo overlay and hosted in on Github.
If you are using Gentoo, adding this overlay is very simple: just add it to
[galdor-overlay] location = /usr/local/portage-galdor sync-type = git sync-uri = git://github.com/galdor/gentoo-overlay.git auto-sync = yes
Then update your local cache with
emerge --sync, or
eix-sync if eix is
You can then install rebar3 like any other package.
