I got it working. I was correct in that it was a build/configuration
issue.
I had to add this to the configuration options at build time:
'--with-mib-modules=tsm-mib'
After that the snmpd started to respond with data:
larryh@apcon-ubuntu:~/.../tls$ snmpget -m +SNMP-TSM-MIB -v 3 -u v3admin -a
md5 -A hello1234 -l authNoPriv 127.0.0.1 1.3.6.1.2.1.190.1.2.1.0
SNMP-TSM-MIB::snmpTsmConfigurationUsePrefix.0 = INTEGER: false(2)
