That obvious, huh? Yeah I'm not from around here. But where I'm from, they don't want me, so that's just as well. Really with my reputation, there aren't many places I can go that'll have me. My own family's blackballed me, and they've got a lot of clout.
Carlyle St. Clair III is a wastelander who was the original candidate for the dish the White Glove Society would dine on for Mortimer's banquet. Before he could get captured by the White Gloves, Carlyle escaped and headed to a shack which became his house. He is very suspicious about outsiders coming to his doorstep and has never left his house since he escaped from the Ultra-Luxe.
Carlyle St. Clair's House is very well camouflaged against the mountain, and can be difficult to find if you don't know how to look. The shack is the same color as the mountain range and is nearly flush up against the mountain. If you have trouble finding the shack where Carlyle St. Clair lives, just follow close to the edge of the east side of the mountain range, beginning just north of North Vegas Square. Teleport to Freeside's Northern Gate and head NE until you see a set of power lines at the base of the mountain range. Follow these power lines until you reach St. Clair's house.

pcps3xbox360 Once you get to the shack, he usually is not there. One solution has worked on PC, but you still may not have access to Carlyle's dialogue tree. Enter the following into the console: prid 127dd7, disable, enable. [verified]
Try knocking out Carlyle, drag his body to the dumpster, and see if the dumpster will let you put his body in. If this doesn't work, enter resetquest 0010d2c6 into the console just after the lines above and then go try knocking him out again after starting the quest over again. This means that you will have to go back to Mortimer and start the events over, and the characters that may have died previously will still be dead.
