The version of ExtUtils::MakeMaker we claim to be shipping in blead is
6.57_05.  There are six changes in blead since 6.57_05 was integrated
(3 by me, 2 by Reini, and 1 by Dave M.).  See:


I *think* all these changes are in upstream at
<> but aren't
in anything released yet.  6.57_06 has been on CPAN since October but
all of these changes are since then, so I think what will happen if
someone installs 5.14.0 and then upgrades EU::MM from CPAN is that
they'll lose these six changes and get a different set of changes.

So do we want to release 5.14.0 with an "experimental" version of
EU::MM?  And if we do, shouldn't we make it a *real* experimental
release rather than an illegitimate child of an experimental release?
And there are also quite a few changes upstream that don't appear to
exist in a release yet, even an experimental one.    Are any of them

Yes, we've been bad about bumping version numbers when we had to patch
something in blead.  But, frankly, I'm afraid to try that because you
have to touch about 30 files and if you don't do it perfectly the
MakeMaker test suite takes revenge.  Plus there's no way to know what
to bump it to since you might be taking a number that will also be
taken by the next, divergent, CPAN release.  So it's really not
practical to bump the version outside of the MakeMaker release
process.   But since MakeMaker is used to build the core, it's also
not always practical to wait for a MakeMaker release to do things that
need doing in core.

I apologize for merely waving a red flag without volunteering to do
anything, but I'm a bit overwhelmed by a pile of actual bugs that need
