Created attachment 164044 [details] Poudriere output showing the problem When building p5-Data-Serializer with the default perl version set to 5.22, the build fails because of a dependency on Module::Build -- for earlier perl versions this was a core module, but with later versions it results in the build trying to use CPAN to install the module.

Ooops. Misspelled the port origin. Fix, and add the maintainer manually.
Is quarterly affected?
Quarterly will behave just the same as HEAD as regards this problem. However, to experience the effect requires non-standard settings for DEFAULT_VERSIONS, so it won't affect quarterly packages and it doesn't have an security implications, so I don't think a MFH is justified.
Actually this was already fixed by adamw in r403628
