Are you sure the module was installed properly? This would include correct installation of Math::Pari, which in turn depends on installation of an external compiled library called "pari".

The module installation should have included some tests, and it is possible to "force" installation despite test failures. If that's what happened in your case, you'll need to try the installation again, and pay attention to the failures.
