Good idea. I added a check for that situation, r9745 on ros/trunk.
It is now a fatal error if the directory in which you're trying to
build a package is not the same (according to Python os.path.realpath)
as where rospack says the package lives.

That's probably not a good idea, because having multiple packages by
the same name in a tree is a common use case for many developers, who
use overlays on top of standard installations. ROS was designed
specifically to support this pattern.
