I found this

and after

linux-hwpu:/home/peter # echo never >
/sys/kernel/mm/transparent_hugepage/enabled
linux-hwpu:/home/peter # echo never >
/sys/kernel/mm/transparent_hugepage/defrag

(and next from any MySQL client as root)
INSTALL SONAME 'ha_tokudb';
SHOW WARNINGS;
-- Warning    1105  Cannot enable tc-log at run-time. XA features of TokuDB
are disabled (so I will need to add it during boot as the link also
describes)
SHOW ENGINES;--and it *IS* there NOW.
