setuid root bit, which is off by default. The purpose is to avoid
having users who don't use kcheckpass become vulnerable to a root
exploit. For more details see the actual pkg-message. Bump PORTREVISION
to reflect this change in the package.
As a side note, I'm a little wary about adding something like this so
close to the ports freeze for 4.4-RELEASE. However, I decided that it
was a minimal risk and went ahead with it in the hopes of avoiding the
need for users to run into this "problem" themselves...
