Changed error messages cause test failures

[fecundf]

I'm building BPM::Engine on Windows, in 64-bit Perl 5.20.1, both Strawberry Perl and ActiveState Perl distributions. Some of the BPM::Engine's tests look for certain failure messages that have changed:

Strawberry:

t/02-store/06-pi-attributes.t line 40. ... new_result expects a hashref ... doesn't match '(?^:needs a hash)'

ActiveState:

t/02-store/06-pi-attributes.t line 40. ... Argument to infer_values_based_on must be a hash ... doesn't match '(?^:needs a hash)'

t/02-store/06-pi-attributes.t line 15. ... object instantiation requires a hashref ... doesn't match '(?^:create needs a hashref)'

Also, since YAML::LibYAML is an indirect dependency, does it need to be listed with a version number? Right now CPAN complains that library has an unparsable version.

None of these will keep BPM::Engine from functioning, so I'm "force install"ing it. Thanks for the library!
