Is that a direct copy and paste of your script? I doubt that this is a problem with File::Copy or using it on OS X. Are you remembering to put the arguments (given that they can contain spaces) in quotes? Take a look at this slight reworking of your example: 
#!/usr/bin/perl
use strict;
use warnings;
use File::Copy;

my $source = $ARGV[0];
my $target = $ARGV[1];
copy($source, $target) or die "Can't copy files ($!) ($?)\n";

I created a file named 'testing spaces.txt' containing some text, and ran the script via 
./copy.pl "testing spaces.txt" output.txt

If you have any further questions let us know

Hope this helps
