Bug fixes:
- When the currently running Module::Build is not the same as the one
that created the Build file, there is now a warning rather than a fatal
error. This helps installation of dependency chains where a dependency
might configure_requires a new Module::Build after Build.PL was already
run for an earlier distribution. [David Golden, on advice of Matt Trout]
Other:
- t/bundle_inc.t fails in odd ways. This test of an experimental feature
should not prevent users from installing Module::Build, so this test
now skips unless $ENV{MB_TEST_EXPERIMENTAL} is true
