I had similar bizarre error messages related to $^V, specifically the
construct sprintf "%vd", $^V, in my case related to CPAN::Reporter for
doing test reports from cpan shell.

This is something related to the $^V being a version.pm object, as it is
in new perls, but the version class not being available for some reason,
hence perl trying to call nonexistant overloaded methods.

Reini, what do you think?
