What about the mysql package? Don't you have to do something to load 
that?

Using the lines above, this is where is breaks. It cannot locate the 
mysql driver. If I add "require 'mysql'", then I get:
DBI::InterfaceError: Could not load driver (uninitialized constant 
Mysql::Driver)
        from c:/ruby/lib/ruby/site_ruby/1.8/dbi.rb:344:in `load_driver'
        from c:/ruby/lib/ruby/site_ruby/1.8/dbi.rb:227:in 
`_get_full_driver'
        from c:/ruby/lib/ruby/site_ruby/1.8/dbi.rb:213:in `connect'

The only correct way I have to initialize these packages for use seems 
to be using the "gem" command, and then I have to require "dbi". Oh 
well. At least it works.

I'm not sure what you mean by package maintainers...
