Updating devel/p5-Moose from 0.90 to 0.91

pkgsrc changes:
  - Adjusting dependencies

Upstream changes:
0.91 Tue, Sep 17, 2009
    * Moose::Object
      - Don't import any functions, in order to avoid polluting our namespace
        with things that can look like methods (blessed, try, etc)
        (nothingmuch)

    * Moose::Meta::Method::Constructor
      - The generated code needs to called Scalar::Util::blessed by its
        fully-qualified name or else Perl can interpret the call to blessed as
        an indirect method call. This broke Search::GIN, which in turn broke
        KiokuDB. (nothingmuch)
