(http://www.freebsd.org/cgi/man.cgi?query=make&apropos=0&sektion=0&manpath=FreeBSD+9.0-RELEASE&arch=default&format=html):
:: If no sources are specified, the target is always re-created.
Otherwise, a target is considered out-of-date if any of its sources
has been modified more recently than the target. Sources for a
target do not accumulate over dependency lines when this operator is
used. The target will not be removed if make is interrupted.
This is typically used in ports for pre-everything target, but have never
seen it on post-install. I don't see why the :: is necessary, either, as
':' should do in this case.
