}While the following is probably even a worse performer than
}C<if( $^O =~ /mac/i ){}> it is nonetheless yet another trick to try:
}
}   if (grep(/\:/,@INC)) {
}		$thePath = "$theDirectory:$theFile";
}		}
}

Not a good idea, because, of course, : is a legal character in Unix
filenames.  For example, what if I named my personal Unix Perl directory
(not that I do, mind you) "My:Perl:Stuff"?  Similarly with grepping for /.

}And I haven't even mentioned C<use Config;> and %Config elements like
}$Config{'osname'}, $Config{'archname'}, etc.

So far as I know, $^O is shorthand for $Config{'osname'}.  The only real
problem with $^O is, AFAIK, the values aren't documented somewhere.  You
should be able to find out from somewhere what the value of $^O is on
platforms you don't have access to, for purposes of writing portable code.
