Ah yes, perhaps CPAN clients should upgrade on conflicts of "Some::Module < 0.123", although this would still cause a circular dependency failure in the case of upgrading dependants.

I'm afraid a warn() in Makefile.PL or diag() in a test script will not be seen by many cpanminus users unless they use the verbose (-v) option. And a die() will be annoying.
