perl -V:version gives you the version like:

        version='5.8.6';

nice and eval-able. :)  But you can just rely on the exit status from

        perl -e 'eval { require 5.006; 1 } or exit 1'

which will be good (0) if the perl is new enough, and bad (1) if the perl is too old. (Perl4 will really barf and give an error as well, but still be an exit 1.)
