That's very interesting.
I was thinking of doing a similar thing, too.

Have you tried to "call" the Swarm simulation indirectly, not through the
perl script? Maybe call a file which call the simulation?
In the PerlScript you can "call" a file on your Home directory which has
within a line like this
---
./swarmSimulation -batchmode
--
(of course with x permission).

I thought  to use shell scripts to do the call of the simulation, not the
Perl script. Maybe when you call the simulation, as you say, you loose, for
some reasons, the evironment variable.
Tomorrow I'll try my idea, and then I'll put the result on  this list.
Best regards.
