6/17    why does my perl break with the following message?
        "use" may clash with future reserved word at ./foo line 3
        syntax error in file ./foo at line 3, next 2 tokens "use strict"
        \_ Because you're not using perl 5.  You will probably have to change
           the first line of the script to show it where perl 5 is installed
           on your system; if you don't have perl 5, you can download it from
           http://www.perl.com/CPAN/authors/id/GBARR/perl5.005_03.tar.gz
