What does 'file $cmd' (the gnu file program) say? is -e true under mod_perl? I'm out of ideas, but if you are certain its not due to different Apache configuration, then maybe sifting though strace output would be worth trying .. and i'm new to mod_perl anyway. Good luck. My errors are often obvious and found right in the places where I am not looking.
