How do I install a CE to send jobs to an existing PBS server on a different machine?

In the site-cfg.h file add the line:
#define PBS_MASTER %pbsservername% where %pbsservername% is the name of the existing pbs server.

This should miraculously take care of all the jobmanager and info provider problems! There will then be lots of problems with the installation of LCG and experiment software required on the WN's. A recipe is being tested for this and more details will be forthcoming.
