Erlang R14B02 in PPA
Erlang R14B02 has been uploaded a few days ago in Debian Unstable, and I have just backported the same packages in my Launchpad PPA, compiled for Ubuntu 10.10 Maverick. I have also added an additional patch that resolves a compilation problem for 64bit architectures, a solution suggested in Erlang bugs mailing list.
As I said in previous occasions, these packages are a direct backport from the Debian repository, without (almost) any other modification; they work in my system, but they may not work for you. I am not the official Erlang maintainer in Ubuntu, and I may not have time to hunt for bugs, so if you find a problem feel free to report it, but it may not be solved (at least in short time).
