mysql, dbi and help please

["james \(home\)" <j@mes.preece.co.uk>]

having installed perl and mysql server etc, I have run my perl script
available.plx and get the results below

<Snip>
ADO
        No known data sources
ExampleP
        dbi:ExampleP:dir=.
Proxy
        Error: install_driver(Proxy) failed: Can't locate RPC/PlClient.pm i
mysql
        No known data sources
</Snip>

Can anyone tell me what I need to do to get dbi talking to mysql, and perl
talking to them both.

Thanks for your help ;-)

James.
