Thanks for writing! This project should definitely build, as it just includes one of our standard bundles. If I remove the Utilities bundle in the project, the build completes successfully.
Was there something that you specifically needed in the Utilities bundle? Perhaps you could add that package individually?
We just discovered the reason ExtUtils-MakeMaker 6.30 showed up in your project; it was a bug in the data which we’ve just fixed. If you return to your project and make any other modification, such as adding another Perl package, you no longer see ExtUtils-MakeMaker as a resolved dependency, at least at version 6.30.
