It looks like you do not have Moose installed. Either look for a .rpm package (using yum search Moose or your favorite package manager), or look at installing via CPAN (perl -MCPAN -e 'install Moose'). Being a CentOS (RedHat-derivative), I would suggest looking for an RPM package first.

If you want a "clean" perl environment, you can look at installing perlbrew.

Hope that helps.
