Hello all, perhaps you may be able to help. I am trying to RTFM for PDL. PDL::Doc is installed but its database appears not to be. This is what happens: 


$ pdldoc -a slice
Unable to find PDL/pdldoc.db in /etc/perl:/usr/local/lib/x86_64-linux-gnu/perl/5.30.0:/usr/local/share/perl/5.30.0:/usr/lib/x86_64-linux-gnu/perl5/5.30:/usr/share/perl5:/usr/lib/x86_64-linux-gnu/perl/5.30:/usr/share/perl/5.30:/usr/local/lib/site_perl:/usr/lib/x86_64-linux-gnu/perl-base

What have I done wrong, and how may I fix it?
