awacha [1] filed a deletion request for perl-pdl-nohdf4 [2]: I have created this package years ago, because at the time there was a conflict between HDF4 and 5 while building the package "demeter", which I maintain. The conflict has been resolved, demeter builds with perl-pdl, therefore there is no need to keep this package anymore.
