[iBook] Dev Kit and backups

[Jean-Paul Thuot]

All this talk of backing up has come just as I bring home a new 
external Firewire HD, and I've been looking for ways to sync it up with 
my home directory using Cron.

I've found this open source app called 'psync' which can be found here:

However, one thing it needs is something called MACOSX::FILE which can 
be found here:

http://search.cpan.org/dist/MacOSX-File/File.pm

The thing I've run into is this cryptic little line:

"To install this module, first make sure Developer kit is installed."

Now, WHICH Developer Kit are they talking about, and how do I know if 
it's installed? I went to the Apple site and found a list of about 15 
different development kits available. One looked useful, called XCode, 
however you must be a member to purchase it and I don't want the hassle 
if I don't absolutely need it.

I come from a mixed Windows/Linux background so I'm not concerned about 
compiling/making the files.  I just don't know what "Developer Kit" 
refers to in this instance.  If someone has an insight into this I'd be 
grateful.

Thanks in advance,

Jean-Paul
