Reinhard, thanks for your excellent workaround - this seems far less intrusive than downgrading libs.
In case it helps anyone else, after a bit of searching I found the file to change to add the nxagent command line arg to a plain NoMachine NX install.
The file is /usr/NX/etc/node.cfg. The property to modify is AgentExtraOptions.
