Message from $pkg:
!!! ATTENTION !!!
You are currently running FreeBSD $vcurr.
Correct operation of $pkg requires a bugfix that was delivered
in $vreq.
This package is probably installed as a dependency of some screen locker,
and without the bugfix, YOU WILL PROBABLY BE UNABLE TO UNLOCK YOUR SCREEN.
Please use freebsd-update(8) to update your system before you continue.
