Oh, to be a monk of high enough ranking to edit your post and add the <code> tags so it would be readable... Regardless...I'll try and help. You did tell perl that Fleece.pm exports things, by:

use Exporter;
[download]

But nowhere do you tell it *what* to export.

@EXPORT = qw( $fleece );
[download]

Or better:

@EXPORT_OK = qw( $fleece );
[download]

This would be slightly better since users would have to specifically ask for $fleece to get it:

use Fleece qw( $fleece );
[download]

It's considered good form to not clutter of someone's namespace recklessly. I'd suggest a read of the Exporter Documentation would help you understand all this a little better. HTH, Jeff
