MB 0.2805/version.pm broken on older bleadperls
When I try to install Module::Build for bleadperl @24713 (a version
from 2005-06-06) then I can't due to the error below. Anybody know the
reason and has an idea for a fix?
Don't tell me that I shall install a newer version of version.pm: This
fails because it depends on Module::Build :(

It's kind of a stretch, though, to try and maintain compatibility with random bleadperl releases, which by default and design are not intended to be considered stable releases. OK, here's the story: back in 2005-06-06, the version object was much simpler (it was just a blessed array). And $^V returned one of those simpler version objects at that time, which Module::Build's version.pm code has no clue how to deal with (it expects version objects to be hashes, not arrays). We can special case this in the Module::Build code, but I'm really not sure it's worth putting it in the released code, since bleadperl has moved on from that time in an incompatible fashion.
