If I go to the PDL CPAN Testers reports page, http://www.cpantesters.org/distro/P/PDL.html#PDL-2.4.10 and select "All Releases" for "Dist Maturity" for Availability->"On CPAN ONLY" then I still see results for PDL-2.4.9_006 and PDL-2.4.9_007 even though both of those are now only on backpan. This anomaly appeared during the rebuild of the CPAN Testers server and I think something may need to be manually cleared.
Thanks, Chris
