It's certainly not necessary for all modules in a distribution to have the same version number, but where the two modules I'm most familiar with (Inline, and Inline::C) do match, I mistakenly assumed that Inline::MakeMaker would as well, and nearly made the mistake of specifying CONFIGURE_REQUIRES => { Inline::MakeMaker => 0.49 }

Ok, actually I did make the mistake, but the output from make was loud enough for me to realize the error before attempting to make test, and make dist. :)

I wouldn't worry about it. Now that I know it's not just an oversight I will sleep just fine tonight.... if it weren't for the other issues (.h, no .h) I can't seem to let go of. haha
