I believe he meant you to run '/sbin/ldconfig', which creates the
appropriate links and caches dynamic library information found in the
directories specified by the ld.so.conf* files, to be used by the
run-time linker.

While, this may work, if I were just building from the torque tarball
and installing into /usr/local, I'd prefer to build the executables
with /usr/local/lib added to their runtime library search path, using
-rpath /usr/local/lib when the software was compiled.  This  isn't
done by the default configure/make, but just set
LDFLAGS="-Wl,-rpath,/usr/local/lib" before running configure. 

I guess I just don't want other binaries on the system looking in
/usr/local/lib when searching for libraries.
