"missing in META.yml, tolerated by PAUSE indexer"

That text appears at https://github.com/andk/pause/blob/master/lib/PAUSE/dist.pm#L558

I received it in an indexer email for the last couple of PDL releases. It looks like PAUSE is fine with "file ne package without version", but not with "file ne package WITH version", which Test::PDL has, being in there as `TestPDL.pm`, because there's already a `PDL.pm`, not too surprisingly.
