Import p5-ExtUtils-MakeMaker-CPANfile-0.06 as devel/p5-ExtUtils-MakeMaker-CPANfile.

ExtUtils::MakeMaker::CPANfile loads cpanfile in your distribution and
modifies parameters for WriteMakefile in your Makefile.PL. Just use it
instead of ExtUtils::MakeMaker (which should be loaded internally),
and prepare cpanfile.
