That may be true as far as it goes, but Moo 1 could not satisfy Dancer 2’s dependencies.  It doesn’t matter if you installed via cpan, cpanm, or a source tarball, the installation should either have resulted in a side-by-side installation of Moo 2, or the installation should have failed.

I just upgraded to 0.201000 on CentOS 5 via cpanm, and the stock “dancer2 -a foo” app runs just fine.

Jochen, did you perhaps do a “force install” via cpan?  If so, I find that installing via cpanm is much more pleasant and reliable, since it follows dependencies by default and suppresses all of the interactive queries cpan passes through from the underlying Perl build system.  With cpanm, the installation either works or doesn’t, and if it doesn’t, there’s usually a good reason why.
