If a module is required, and thusly creates a cascade of dependencies, there is not much you can do.

You can try installing each module on its own via CPAN, or via the untar'd directory in /root/.cpan/build directory (assuming you /are/ root when doing this.

There are 'force' and 'notest' pragmas one may use when installing modules, but I don't recommend this.

If you determine there is a problem with a particular module, you'll most likely need to contact the maintainer.
