1: Please put <code> tags around the code. This will preserve line breaks and number lines, making it much easier to read.

2: It looks like long lines have been wrapped by adding a + and going to a new line. Perl sees the newline as the end of a comment, and the +====... as a +== operator (which doesn't exist), and some other garbage, and gets very confused. If you got this code from this site, use the "d/l code" link at the bottom of the node, which will give you the code just as the author intended it. (Or at least, as he typed it, which isn't always quite the same thing..)

BTW, I doubt this problem has anything to do with this being on a Mac OS X box.
