PHP4 problem

["Brooks R. Robinson" <brooks.robinson@rides.com>]

Greetings,
	I am trying to test eZtrade (http://trade.ez.no) with debian, and I have
hit a snag.  When the site tries to come up, I get this message:

Fatal error:  Call to undefined function:  mysql_pconnect()

	This is a valid function in both php3 and php4, so what am I missing?

Thanks,

Brooks
