Earlier versions of FreeBSD (5.4) came with PERL support preinstalled. However with FreeBSD 6.x, PERL support must be installed prior to configuration.
Run the following commands..
Down arrow to Perl5 and press Enter
Use spacebar to select perl-5.8.8 - OK
Tab to Install - OK
X to exit - OK
X to exit the installer
You may now continue with the PERL Configuration..
