Which is what I expected, while on a Linux machine, I only get the I am here!...

Odd, works just fine for me. Maybe you should try running it in the debugger. Since the relevant code is in a BEGIN block, you need to put

        BEGIN {
            $DB::single = 1;
            ...

in there to make sure the debugger doesn't just jump over it. Then, call

    $ perl -d move_data.pl

from the command line and step through the source lines using n and s.
