The real problem here is the incredibly strong conflicts in the various erlang packages against erlang-doc-html. Since erlang-doc-html isn't part of the set of erlang packages, I really don't think that conflict is correct. I've filed a bug against the Debian package saying as much, and encouraging the maintainer to drop those conflicts, which will keep the problem from reoccurring going forward.
