Conversely, if you have no intentions of releasing your code to CPAN, you may decide to avoid the nightmare of the unnecessary, undocumented, unarchitected, unfathomable, unmaintainable, over-elaborate, rotting festering mess that is ExeUtils::MakeMaker completely.

And for anything you do have a hankering to release to CPAN, spend an hour or two trying to understand what the hell is going on when you run the Makefile.pl for any moderately complex CPAN module, and try to imagine the trouble you are going to have to incorporate any extra customs steps.

For example, say you would rather have your build process extract the files directly from your source code repository? Rather than having to do this as an extra manual step, with the inherent weakness of forcing the duplication of your source tree and/or imposing the convoluted pattern that is the 'blib' phenomena upon your source tree structure. Look hard and think very carefully how you would modify EU::MM to do this?

Of course, I (infamously) do not have any CPAN modules to my credit, so I may be just crying wolf, so I urge you to look at and think about the problems this route would cause you. Also, take a look around at some of the comments made about the ExtUtils::MakeMaker module by it's current maintainer.

And if the Module::Build route looks interesting, have a good look around at the internecine struggle between it's proponents and the EU::MM diehards.
