If that says the file doesn't exist then the error is correct.
Is the start of a script, the file after the #! is the binary (executable) that interprets the script. You'll generally see either /usr/bin/sh or /usr/bin/bash or /usr/bin/perl
If you don't have perl you should install it. I'm surprised you don't though. try to type in:
If it finds anything, change the file after #! to point to the new one, or make a symmlink to /usr/bin/perl from whatever which found.
