agreed. but that's not the problem. (gotcha!)
as you know...
$ filename
entered like this, it's being run as a command, so it would need +x permissions.
$ perl filename
this way, perl reads the file and then runs the script therein, as long as it's
readable. (a file doesn't need to be executable unless you're trying to run it
as a shell command.)
perl can even run commands from STDIN, such as
$ perl < filename
$ cat filename | perl
so it only needs to be able to READ the file; execute permissions are for the
commands to be run directly from the shell. (saves us lazy folk from typing
a few keystrokes here and there.)

still, when i have perl run the file directly (no chmod +x needed there)
it still bombs with

what's up with that?
