It looks like there is an accidental file collision in foo2zjs and foomatic-db 6.1 release packages. Is there an easy workaround?
# pkg_add foo2zjs quirks-2.304 signed on 2017-04-02T15:01:33Z foo2zjs-20140627p1:foomatic-db-4.0.20161003: ok foo2zjs-20140627p1:foomatic-db-engine-4.0.12p1: ok foo2zjs-20140627p1:cups-filters-1.13.4p0: ok Collision in foo2zjs-20140627p1: the following files already exist /usr/local/share/foomatic/db/source/driver/foo2hiperc-z1.xml (foomatic-db-4.0.20161003 and foo2zjs-20140627p1) The following new rcscripts were installed: /etc/rc.d/cups_browsed See rcctl(8) for details. Look in /usr/local/share/doc/pkg-readmes for extra documentation. I saw the same error during pkg_add -u. Above output is where I tried to reinstall after removing both packages.
