No it was almost twice as many lines. But I think that is where the

I just tried it and that has fixed my problem. I had no clue that
perl was sensitive to carriage returns.
As far as I know, it's not. The problem you run in to is that the
kernel *is* sensitive to CR in the shebang. If the first line of your
file is:
#!/usr/bin/perl\r\n
...then the kernel will try to exec "/usr/bin/perl\r", which doesn't
exist. Naturally, as a kernel issue, this affects all scripts,
regardless of the interpreter used.
..which is why it's a good idea to always use:
#!/usr/bin/perl --
..as the shebang line, which won't get messed up by any combination of
line endings.
