hi,
You're a day too early. Try Module::Build 0.2808, just released to CPAN yesterday afternoon, and the test failures should go away. The short answer is that the behavior of version objects changed (against my better judgement) in version-0.72XX, and the testfiles in M::B needed to be updated.
as advertised, latest "install Module::Build::Version" now seems OK, module_info Module::Build Name: Module::Build Version: 0.2808 Directory: /usr/local/lib/perl/sitelib File: /usr/local/lib/perl/sitelib/Module/Build.pm Core module: no module_info Module::Build::Version Name: Module::Build::Version Version: 0.7203 Directory: /usr/local/lib/perl/sitelib File: /usr/local/lib/perl/sitelib/Module/Build/Version.pm Core module: no thanks!
Additionally, the 'r' option to cpan is somewhat misleading; in this case, the only place that M::B::Version 0.58 existed was in bleadperl, so you couldn't install it into 5.8.8 if you tried. The latest M::B release fixes that as well.
now, that should probably be obvious to me from something in the cpan console ouput, but that completely eluded me. thanks again!
