I use TinyPerl 5.8 on my computer. I don't know if that would meet your needs, but it does meet my needs. It only takes up 30MB of space on my hard drive. I just unzip it, and it's ready to run in 10 seconds. I have set it up so when I click on a .pl file or .cgi file, it automatically runs that Perl program, which is neat since I don't like to call Perl from command line.
