dtrace depends_on pragma should search all library paths, not just the current one
DTrace currently only searches the current directory when looking for dependencies specified by #pragma D depends_on library. The most annoying symptom of this is that if you use such a pragma in a directory specified with -L it has no access to the files in /usr/lib/dtrace. This is a long standing bug fixed by rm at Joyent. We should take their fix from the Joyent tree.
