[erlang-questions] Emacs Distel error "Module is not interpreted, can't set breakpoints." after interpreting

[Robert Dionne]

it can be finnicky. Some things to try:

the version that is in github. I forked this one: http://github.com/kunley/distel

use -sname when starting and specify that name when connecting

does C-c C-d l  work? It show a list of processes.

who calls acts up (C-c C-d w) and I find the best way to make it work  
is to call the function once directly from the erl vm, .eg.  
distel:who_calls(my_module,my_fun,arity).

I'm running R12B01 on OS X 10.6

Cheers,

Bob
