perl5.8 problem?

After more testing it looks like I gave you some bad advice.

On the one hand, it should be 'use Mac::Files;', not 'use Files;', but on 
the other I haven't been able to get this to work with either 'use lib 
<directory>' or with '-I<directory>' on the command line.

So it looks like something is needed when Perl is compiled that's missing 
in the Macports version - which makes sense, given the Macports philosophy 
of not using anyting that Macports didn't build.

What does work (in my testing) is to use the native Perl rather than the 
Macports Perl - i.e. start your script with:

 	#!/usr/bin/perl

instead of

 	#!/opt/local/bin/perl

(or invoke it with '/usr/bin/perl <script>' rather than 'perl <script>', 
assuming /opt/local/bin preceeds /usr/bin in your path).

This may mean that you'd have to do something like this if you want to use 
any Macports-generated Perl modules:

 	use lib '/opt/local/lib/perl5/5.8.8';
 	use <perl module name>;

I suspect it would also work if you created symlinks to the native modules 
in the appropriate places within the /opt/local/lib/perl5 directory tree; 
but this isn't exactly maintainable...
