I find Distel[1], which extends emacs, to be a very good IDE for erlang. It connects to a running
erlang VM and accesses the code module, to produce support for symbolic debugging, listing
processes, etc.. There is a bug in who_calls, one of the more valuable features. You can work
around it by invoking who_calls once from the VM directly, .eg. distel:who_call(couch_uuids,new,0).
and thereafter C-c C-d w   will do the right thing. This is very useful for navigating the
code paths.

There are some docs[2] that aren't complete, but will get you started
