[erlang-questions] autoconf and erlang

[jm]

In attempting to package up my inotify port for erlang I'm using or 
rather trying to use autoconf and automake. I've sort of got it working 
for the C part of the code but not for the erlang parts. Based on Romain 
Lenglet's "Using GNU Autoconf to Configure Erlang Programs" EUC 2006 
presentation slides I've ended up with the configure.ac shown below.

My questions are:

1) How do I work out where to put the beam files and the compiled c-port?
2) What is the best way to alter the code so that the open_port() 
function knowns what to execute? At the moment, there's a

    -define(PORTPROG, "./inotify").

near the top of the erlang source file. Include file? How do i go about 
finding the correct path and inserting this automatically?

3) Any good similar examples out there that can be used as a reference 
for a starting point?

4) Any other suggestions?

#                                               -*- Autoconf -*-
# Process this file with autoconf to produce a configure script.
