Erlang is not installed (as recommended from the ticket); but, attempts are continuously made to install resulting in a failure to upgrade the entire installed list.  Under the current structure, it seems impossible to determine which port requires erlang (no list of dependencies provided at the beginning of each upgrade or installation in the debug listing).  Is there a way to get a dependency tree for installed ports?

There's the "port rdeps" command, or if you'd like it graphically, the "port_depgraph" script:

You could also post (or attach to a ticket) the failed erlang build log.
