MI cannot handle EUMM being at a dev version

This is with the latest version of MI installed (1.10):

There are two things happening here. First is that Module::Install writes the current version of ExtUtils::MakeMaker (as taken from $ExtUtils::MakeMaker::VERSION) into configure_requires. This seems mostly unnecessary but isn't really wrong. This version number doesn't include the underscore.

The version is then checked by cpanm, which uses version.pm for version comparisons. And version.pm still treats versions with underscores incorrectly.

If it didn't do this, we wouldn't be running into this problem.
Unnecessary prereqs cause unnecessary churn on everything downstream. It
would be better if MI only declared a EUMM dependency that it actually
needed for a particular feature (e.g. a WriteMakefile argument). The
minimum version required for each feature is clearly documented in EUMM's
main pod.

The version is then checked by cpanm, which uses version.pm for version comparisons. And version.pm still treats versions with underscores incorrectly.

Yeah, I really wish we could get that fixed... :/ Underscores are not
supposed to be significant, and we have conversations back in 2001
confirming that intent.

I just double checked, and Module::Install no longer inserts the current EUMM as a configure_requires. The modules you ran into problems with need to be refreshed with a modern MI.
