Anyone noticed this strange --version thing?

# make update
===> Resuming update for gnome-session-2.10.0
===> *** No /usr/pkgsrc/distfiles/pkg-vulnerabilities file found,
===> *** skipping vulnerability checks. To fix, install
===> *** the pkgsrc/security/audit-packages package and run
===> *** '/usr/pkg/sbin/download-vulnerability-list'.
===> Installing for gnome-session-2.10.0
--version: not found
...

Installation seems to continue fine.
