You did not upgrade correctly, see explanation below. To repair this, you need to run the extra build steps. Use a CPAN client to automate this. Force the installation if necessary.

You are getting the error message because the compiled XS part does not match the Perl part of the modules. You upgraded one, but not the other. It is wrong to just copy .pm files around.
