pkgdb perl unknown modifier

["Daniel Dvořák$"]

Hi all,

I would like to ask about this strange error output of pkgdb command. I 
think something terrible wrong with perl, but if I want to upgrade it, 
it fails at the same place. So another commands like portversion or 
portupgrade have the same error output like pkgdb.

pkgdb -F

I hope this mailling list is right place where I can ask for help for 
error like that. If this is not right place, I am sorry for that. May I 
ask you to guide me to the right mailling list ?

Thank you.

Best regards,

Daniel

Merry Christmas !!!
