Sadly the only "true" dps build is this one
http://www.guildwars2guru.com/topic/...-ranger-build/ (or something similar anyway) where you focus heavily on auto-attacks.
There's a couple of BM builds out there that work though but I personally don't like the playstyle, here's an example
http://gw2skills.net/editor/?fMAQNBh...mqkIq2bQEVDA-e (only check traits, I didn't fix the rest).
For actually using ranged weapons there's the clasic 30/30/x/0/x build put the last points on your prefered x, but I again don't like this. If you go with 30in marks you basically take the "signet of the beastmaster" trait which sucks imo since you don't want to activate most signets anyway. I personally prefer 25/30/0/0/15.
All these builds are designed around the SB though since LB dmg is laughable.
