PBS is annoying. Here's the deal: When environment variables have commas in 
them, it causes problems with PBS. (I'm not sure which version of PBS: 
Maarten, can you comment?) GLOBUS_TCP_PORT_RANGE has commas in it, so it is a 
regular source of problems.

The right way to fix this may be to scan the environment for any variables 
that have commas in them, and remove them from the environment. In lieu of 
that, this is a patch that just undefined GLOBUS_TCP_PORT_RANGE. It's an 
incomplete solution, but it helps many of the problems, so it's useful. 

We'd like to either see this hack added, or a better solution developed. We're 
happy to work with you to develop something better, if you would prefer.

Thanks!
