Ubuntu 10.04 ejabberd with mysql

Hi guys and thanks for all of your kind help so far.
I am working on getting my ejabberd to work using mysql
Here is what I have been successful with so far:

1. Creating the ejabberd db on mysql server
2. establishing the ejabbed mysql user
3. compiling the beam files for the odbc connection

The only thing I am trying to clarify now is the correct location for the beam files
with the deb package install on ubuntu 10.04 server.

The INSTALL file mentions two possible paths

/lib/ejabberd/ebin

or

/var/lib/ejabberd/ebin

no ebin folders exist there however i did a search and found a few possibilities where beam filesw exist which include:

/usr/lib/erlang/lib/stdlib-1.16.4/ebin
/usr/lib/erlang/odbc-2.10.6/ebin ---- is this the correct place for me to place my build beam files for mysql (my guess is yes)
/usr/lib/erlang/lib/ssl-3.10.7/ebin
/usr/lib/erlang/runtime_tools-1.8.2/ebin

Thanks in advance for any assistance or pointing to someone elses breadcrumbs
