[erlang-questions] Using Dialyzer on Ubuntu 9.10?

I've installed the Erlang packages with the erlang-dev ppa and the dialyzer
is happy. I'd love to see the newer Erlang releases available also as you
suggest in the bug comments. Is this much work to do?

Also where would one locate the general information about the Ubuntu Erlang
packages? I'd be great if the info on adding the Erlang dev ppa were
available wherever the normal documentation is for this. Had these ppa been
available earlier where would I have looked to know of it's existence? Where
can I get info on updates?

Thanks a lot. Your quick responses and support on this are much appreciated!
