yes, i eventually figured that out.  unfortunately, i got roadblocked trying to get OTP
and pico (which our xmlrpc server was built on top of) to play nicely together, and i ran out
of the limited time i had to spend in converting our old vanilla erlang app to OTP.

it's a real shame, since i think OTP is a natural for the kind of things i need to do.
but the learning curve is steep, most of the contrib tools don't use it, and i don't 
get much time to play with erlang.  i got pretty close this time, getting my main
stuff to build, install, and run, but without xmlrpc no one could talk to it, so i had
to punt back to the old code.
