Just updated my google command line script to remove the dependency on the GPL'd Ruby/Google, as well as any other external libraries. All it needs now is a recent version (I am using 1.8.2) of ruby =)
brianm@kite:~$ google -h
Usage: google [options] query string which will be concatenated
Options:
-i, --start NUMBER Start index for results
-m, --max NUMBER Max number of results to show
-f, --[no-]filter Activates or deactivates automatic results filtering
-r, --restrict VALUE Restricts the search
-a, --[no-]safe Enable or disable (default disabled) filtering of adult content
-1, --lucky I'm feeling lucky
-H, --header Print field header on ouput (default disabled)
-s, --snippet Display result snippet in output
-t, --title Display result title in output
-u, --[no-]url Show or hide result url in output
-h, --help Show this message
Requires Ruby 1.8.1 and Ruby/Google ( http://www.caliban.org/ruby/ruby-google.shtml )
You can obtain a (free!) google key from http://www.google.com/apis/
exit

Have fun!
