DBI:ODBC on Vista: "could not load driver"

The following code, run from NetBeans IDE on Vista SP1 Home Edition:
p require(‘dbi’)
p require(‘odbc’)
p DBI.available_drivers
dbh= DBI.connect(‘dbi:ODBC:cookbook’,‘root’)

Produces:
true
true
[“dbi:Proxy:”, “dbi:ODBC:”]

‘cookbook’ (from InstantRails, which is running)is a data source with a
32-bit Mysql ODBC driver, v5.1, installed with the SysWOW data source
installer.

Where do I go from here?

Thanks in advance for your kindness.

I’d make sure the ruby odbc example scripts work [and maybe ditch odbc
altogether what is that anyway?]
