FreeBSD-current is, quite literally, nothing more than a daily snapshot of the working sources for FreeBSD. These include work in progress, experimental changes and transitional mechanisms that may or may not be present in the next official release of the software. While many of us compile almost daily from FreeBSD-current sources, there are periods of time when the sources are literally uncompilable. These problems are generally resolved as expeditiously as possible, but whether or not FreeBSD-current sources bring disaster or greatly desired functionality can literally be a matter of which part of any given 24 hour period you grabbed them in!
Under certain circumstances we will sometimes make binaries for parts of FreeBSD-current available, but only because we're interested in getting something tested, not because we're in the business of providing binary releases of current. If we don't offer, please don't ask! It takes far too much time to do this as a general task.
