problem with odbc

Hi,

I'm trying to install livesupport on Fedora Core 3. Compilation and install seem to go ok but when I try to start the scheduler I get this error:
$ bin/scheduler.sh start

error executing command start
database installation problem: Failed to connect to datasource: [unixODBC][Driver Manager]Data source name not found, and no default driver specified

Are there clear instructions someplace for how to configure ODBC? I followed the install documentation and used this configure command:
./configure --prefix=/usr/local/livesupport --with-apache-group=apache
--with-create-odbc-data-source --with-www-docroot=/var/www/html
--with-create-database --with-init-database --with-configure-apache

I have unixODBC and postgresql-odbc installed along with the other required stuff.

Any help is greatly appreciated.
Thanks!
