The textproc/docproj package should depend on textproc/groff. Otherwise, on a clean system, after "pkg install docproj", trying to build the Handbook one gets: tmpfile=$(mktemp /usr/home/trasz/svn-ssh/doc/en_US.ISO8859-1/books/handbook/../../../share/images/books/handbook/advanced-networking/net-routing.ps.XXXXXXXX); groff -p -S -Wall -mtty-char -man /usr/home/trasz/svn-ssh/doc/en_US.ISO8859-1/books/handbook/../../../share/images/books/handbook/advanced-networking/net-routing.pic > $tmpfile && /bin/mv -f $tmpfile /usr/home/trasz/svn-ssh/doc/en_US.ISO8859-1/books/handbook/../../../share/images/books/handbook/advanced-networking/net-routing.ps /bin/sh: groff: not found *** Error code 127 Stop. make: stopped in /usr/home/trasz/svn-ssh/doc/en_US.ISO8859-1/books/handbook
