in reply to Diagnosing error report: "IO object version 1.21 does not match bootstrap parameter 1.22"
As I understand it, that error means that the version in the XS portion of IO does not match the version in the Perl portion of the module. It sounds like an incorrect installation of Perl -- I don't think this is your fault or something you should feel an obligation to support.
