From what I can tell by your CPAN layout, your directory structure should look like this:

lib
  /RandomJungle
             /File
                  |- DB.pm
                  |- OOB.pm
                  |- RAW.pm
                  |- XML.pm
             /Tree
                  |- Node.pm
             |- Tree.pm 
             |- Jungle.pm
             |- TestData.pm

Congrats on your first upload btw! For me, it was a stressful thing to do, and it took me a very long time and very much research before my first one :)

Update: Let us know when you've got it updated and I'll install and test it.
