Practically every week, while using the cpan shell, I'm prompted to upgrade to the latest version of Bundle::CPAN. But this is often not a clean process. Most often the obstacles have to do with signature verifications -- an issue I do not claim to understand very well.

Tonight, for instance, I got the following summary after calling install Bundle::CPAN: 

Bundle summary: The following items in bundle Bundle::CPAN had install
+ation problems:
  File::Spec Module::Build CPAN 
Failed during this command:
  KWILLIAMS/PathTools-3.17.tar.gz              : signature_verify NO
  ANDK/CPAN-1.87.tar.gz                        : signature_verify NO
  KWILLIAMS/Module-Build-0.2612.tar.gz         : signature_verify NO

When I then went to install the individual components separately, I got error messages like this: 

cpan> install File::Spec
Running install for module File::Spec
Running make for K/KW/KWILLIAMS/PathTools-3.17.tar.gz
  Is already unwrapped into directory /Users/jimk/.cpan/build/PathTool
+s-3.17
  Did not pass the signature test.
Running make test
  Make had some problems, won't test
Running make install
  Make had some problems, won't install

Needless to say, these are all modules that I have long had installed and upgraded repeatedly.

What is the best way of responding to these signature_verify NO errors?

Thanks in advance.
