Ryan,

I don't see either the 'Use of initialized' error or the massive  
failed test issue using Mac OS X (perl 5.8).  I get a different set of  
warnings using perl 5.10 related to Data::Dumper but not this (and  
everything runs fine).

It might be of help to know what perl version, OS, etc. you are  
using.  It also might be worth upgrading Module::Build and  
Test::Harness as well (though the Build.PL script should catch that  
and warn you).
