You can force print() to print unbuffered like this: 

$| = 1;

perl -e 'use v5.10; $| = 1; for (1..10) {print $_; sleep(1);}'

I was looking for a link to the docs to share with you and found this oldie but goodie from the Perl Cookbook: Recipe 7.19. Flushing Output :-)

Hope this helps!

update: Changed link to Perl Cookbook excerpt since the one I originally posted turned out to be to a pirate site! (Of course some might use the same description for Google Books ... but the ORA permission is right there.) I just thought it would be fun to post an example from a classic text; next time I'll stick to the current perldoc, I think.
The way forward always starts with a minimal test.
