This process needs a valid environment (e.g PATH variable and others) in order to find the Perl run-time system, the required commands and libraries and so on.
If the process does not have a valid environment, it will fail. You can test that manually by logging on to the server, and running the command unset PATH before executing the Perl script.
One approach to this, is not to call something like the perl script directly. Instead create a shell wrapper script. In this script set a valid environment and then have it execute the perl script with the required command line parameters. Typically a shell script can always be executed (despite minimal environment settings), as long as you fully qualify the location (path) of the script.
