 Installing perl fails with
 
 pkg_add: Failed to write bin/perl5.30.0 for perl-5.30.0nb1: Could not 
 open bin/perl
 pkg_add: Couldn't remove /opt/local/bin/perl5.30.0
 pkg_add: Couldn't remove /opt/local/lib/perl5/5.30.0/AnyDBM_File.pm
 pkg_add: Couldn't remove /opt/local/lib/perl5/5.30.0/App/Cpan.pm
 [...]
 pkg_add: Couldn't remove /opt/local/lib/perl5/man/man3/warnings::register.3
 pkg_add: 1 package addition failed
 
 i.e. unpacking the archive fails to hard-link perl5.30.0 tp perl, and 
 pkg_add proceeds to roll back the installation.
 
 A "ktrace -di pkg_add /var/obj/pkgsrc/packages/All/perl-5.30.0nb1.tgz" gives
