Actually, "ldconfig" is the tool that updates the linking path cache
based on what's in /etc/ld.so.conf.  I think he meant you to run
ldconfig after you made sure /usr/local/lib was in /etc/ld.so.conf.

One way to tell what's going on is to use the "ldd" command.  It'll tell
you which libraries the binary needs, and if/where it found them.  So,
if your "qstat" and "qsub", etc., are in /usr/local/bin/, you could run
this:


ldd /usr/local/bin/qstat

or

ldd /usr/local/bin/qsub



If you see any "not found" messages, that's the problem.  The ld.so.conf
and ldconfig stuff is a way of updating the cache, so the ldd command
again after running ldconfig as root.
