In Perl \n is the local system's linebreak, whatever it is.  On Unix 
\n == \012, and under Mac OS \n == \015.  This choice for \n makes 
scripts more portable, so that they'll do the "right thing" on any 
platform.  But there are time when you need to be explicit, and this 
is one of them.  If you do the above split on a Unix file using 
MacPerl, nothing will split.

Personally, I'd read a Unix file into an array with MacPerl like this:

$/ = '\012';
chomp(@lines = <FILEHANDLE>);
