Did a little digging and from the bottom distel:find_source/1 certainly
seems to find the source file (by the
path /top/project/application/source.erl) correctly, so maybe there is
something else going one unrelated to the source tree, or possibly
tangentially related.  Here is the actual error I get in the
*erl-output* buffer that is created when I toggle on interactive:

** Invalid beam file or no abstract code:
"/top/project/application/source.erl"

I cannot find (with simple grep searching for either "Invalid beam file"
or "no abstract code") where this message is generated in either the
lisp or the erlang code for distel. A pointer to the right place to look
would be greatly appreciated.


thanks,
