I need to make some system calls to other programs from a perl program
and those programs that are being called have some environment
variable dependencies that are set by a shell script program. So I
have to call this shell script to set up (set variables)
environment variables so that the other program that I call can run fine.
when calling the command script on the command line, I see these environment variables aren't being passed and die with errors. (ie doesn't understand setenv command)
