Help desperately needed installing DBI module.

I'm a newbie and I need help with the DBI module.  I have downloaded the module and it's a tar.gz file.  I need clear, step-by-step directions on how to unzip and install the module for use in my 7.04 Ubuntu installation.  I'd appreciate any and all assistance.

here's your lunchbox  link goes to the section on install from source, but the whole page is awesomely useful for newbs.
