A lot of it depends on what OS you're performing this on. *BSD has the ports/pkgsrc system, depending which specific BSD you're doing this on. In FreeBSD (the one I use and the only one I can speak for) it's a cinch. In Linux, I'm not sure that it would be a problem either, by way of grabbing source or your flavor of package. Other OS's I can't speak too well for. =]
