Dumb as a wedge when it comes to installing ffmpeg

Could someone please tell me where I could find some info on how to incorporate alienbob's ffmpeg build into my slackware? I see builds and packages and I'm totally clueless as to how to make the magic happen. I swear I've tried to google the pertinent info but I can't seem to find it anywhere :-/ (feel free to tell me to get a clue, noob)
