A couple of weeks ago, a new major version of the Erlang runtime system and libraries has been released, and after its inclusion in the Experimental branch of Debian, I have ported it to Ubuntu 11.10 and published the packages on my PPA.
The packages are the same of the Debian release, I have not changed anything; I don’t know if I will have time to backport it to the previous Ubuntu releases, especially because I am not using them anymore. As usual, IWFM: if you experience any problems, you can report them to me, but as I am not an official maintainer, I don’t know if I will be able to solve them
