Gah, I'm getting errors like this

Error: Weak references are not implemented in the version of perl at

This pretty much means that the packages Scalar::Util and Compress::Zlib are outdated and need to be updated. First and obvious thing to do is to use cpan to re-install the broken modules, but unfortunately if you try and re-install Compress::Zlib from cpan it will get into a circular dependancy. The best thing to do is probably manually update/reinstall the following packages.

Go to cpan and grab a copy of

• Compress::Zlib
• Scalar::List::Utils
• IO::Compress

and then install them by hand.
