The dependencies themselves are stored as @pkgdep lines in the
/var/db/pkg/packagename/+CONTENTS file.  The reverse link is stored in
/var/db/pkg/packagename/+REQUIRED_BY .  You can list the dependencies
with the "pkg_info -r packagename" command, and the packages that
require a package with "pkg_info -R packagename".
