[mariadb-10.1] missing file in installation

[Bjarne D Mathiesen]

I've just installed mariadb-10.1-server

It fails on starting the server with :

=> cd '/macports' ; /macports/lib/mariadb-10.1/bin/mysqld_safe
--datadir='/Volumes/BrugerData/MaraiDB/'

#=> tail /Volumes/BrugerData/MaraiDB//0125000629.4.fullrate.ninja.err

ls: /macports/lib/mariadb-10.1/share/mariadb-10.1/errmsg.sys: No such
file or directory

This file is missing in the installation on three different computers.
It's also not present in mariadb-10.0

How do I fix this ?
