DBD::ODBC on linux

[david_dick at iprimus.com.au]

G'day all,
Nearly tearing proverbial hair out here.  There are weird and wonderful reasons I need to do this, but skipping directly to the problem, has anyone had a successful experience of connecting via DBD::ODBC from a script on a linux box to a mysql database?
If so, what is the format of the dsn? 
I have installed the mysql odbc driver, the iodbc driver manager and just can't get DBD::ODBC to understand what i am trying to do. :)
