in thread problem referencing global variable in self-written module

Print $INC{'Fleece.pm'} to make sure you are using the Fleece.pm you think you are using.

Perl Monks assumes everything in code tags is Perl code, and it can't tell the diff between code which should be a in .pm and other code. For use Fleece to work, you'll need to name the file Fleece.pm.
