This is a change to the PAUSE indexer. It's no longer indexing things that are world-writeable. See the recent threads on the perl-qa list, especially Dealing with World-writable Files in the Archive of CPANDistributions, as well as the discussion on use.perl.

The fix is to find out which tar you are using and how to set its default permissions, even if you are on Windows. Although Windows doesn't have the idea of unixy permissions, the things it tars up untar in certain ways on Unix.

Good luck, :)
