This looks pretty abysmal and doesn't match up with the CPAN Testers results for NetAddr::IP 4.007. Please make sure you have all prerequisites installed:

perl Makefile.PL
[download]

will list all modules which NetAddr::IP needs that are missing in your Perl distribution. You need to install these as well. The cpan tool will do that autmatically for you.

If you are sure that you have all the right prerequisites installed already, you can run the tests in isolation or in verbose mode to see why they are failing:

perl -Ilib -w t/wildcard.t
[download]

will run a test stand-alone and

make test TEST_VERBOSE=1
[download]

will show you all tests and how they fail. Post the output of at least one of the two, preferrably only of one test program, because likely there is some fundamental failure with one of the underlying Perl modules.
