The perlport man page contains a brief bit about this.  (The full title of
the man page is "Writing Portable Perl.")  You can find the full page at the
following URL:

http://www.perl.com/pub/doc/manual/html/pod/perlport.html#S_Mac_OS_

The appropriate section is this:

"In the MacPerl application, you can't run a program from the command line;
programs that expect @ARGV to be populated can be edited with something like
the following, which brings up a dialog box asking for the command line
arguments. 
    if (!@ARGV) {
        @ARGV = split /\s+/, MacPerl::Ask('Arguments?');
    }

A MacPerl script saved as a droplet will populate @ARGV with the full
pathnames of the files dropped onto the script.
Mac users can use programs on a kind of command line under MPW (Macintosh
Programmer's Workshop, a free development environment from Apple). MacPerl
was first introduced as an MPW tool, and MPW can be used like a shell:
    perl myscript.plx some arguments

ToolServer is another app from Apple that provides access to MPW tools from
MPW and the MacPerl app, which allows MacPerl programs to use system,
backticks, and piped open."
