This warning is exactly what it says.  The script declared a variable with
my, and then declared it again with my in the same scope.

perldiag:

    "my" variable %s masks earlier declaration in same %s

        (W) A lexical variable has been redeclared in the current scope or
        statement, effectively eliminating all access to the previous
        instance.  This is almost always a typographical error.  Note that
        the earlier variable will still exist until the end of the scope or
        until all closure referents to it are destroyed.


This is not specific to running the script in MacPerl; it's just a poorly
written script that the author never tested with -w.  You can turn off
warnings, or remove the extra my declarations.  Or download or write a
better script.  :)
