Can't locate object method "new" via package "MD5"

I've managed to get around my initial problems of a few days ago by
installing an update of the dev tools, but am now facing a new problem.

I'm trying to install MD5, here's the output:

===snip===

Is this a catch 22 - you can't install MD5 without MD5, or is it something
else? I got this same error when trying to install MIME::Tools and also
Digest::MD5 as mentioned in the output.

Any ideas?
