YAML should be a PREREQ_PM because it is used in lib/Crane/Config.pm.
Makefile.PL contains a TEST_REQUIRES, MakeMaker should be declared as a configure_requires with a minimum version of which version introduced TEST_REQUIRES, which is 6.6303 (see https://metacpan.org/changes/distribution/ExtUtils-MakeMaker#L437)
