Personally, I prefer not to have "developer" configuration (also passwords) in the program. I either put those into a configuration file or take them from %ENV.
Taking them from %ENV sounds interesting. If i understood well, it would mean that as a default, $I_AM_DEV would be set to 0, and that on my computer, it would be set to 1 through an environmental variable. Thus, i wouldn't need to change it each time i'm passing him the program (i also just send him the .pl file when there are no new prerequisites).
Did i understand what you are doing properly ?
