The parrot homepage http://www.parrotcode.org/ currently says Periodic releases will appear on CPAN; the current release is version 0.0.10, and can be found in the CPAN source directory. And "source directory" is a link to parrot-0.0.10.tar.gz
The similarity in release numbers is particularly unfortunate. Sorry I missed that when looking at the page. (Saw "source directory", thought "ah, users will see the more recent releases in the directory"). Updating the homepage soon would seem desirable. Mitchell
