| Subject: | Distribution includes both a Makefile.PL and Bild.PL |
Providing both files is generally not a good idea -- e.g. see http://neilb.org/2015/05/18/two-build-files-considered-harmful.html
Since you are using Dist::Zilla, it is a simple matter to simply drop the use of [ModuleBuild].
(Additionally, there is no value in constructing a MANIFEST.SKIP in dist.ini. This file is only used for packagers, and Dist::Zilla has better ways of figuring out what files to include/exclude.)
