Just like in https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=269909
opensearch once again fails to build when disabling plugins:

===>   Building opensearch-2.11.1

Stop.
make: stopped in /usr/ports/textproc/opensearch


At a first glance, in the Makefile

        ${ECHO} "@dir(opensearch,opensearch,0750) ${ETCDIR}/opensearch-notifications-core" >> ${TMPPLIST}
        ${ECHO} "@dir(opensearch,opensearch,0750) ${ETCDIR}/opensearch-notifications" >> ${TMPPLIST}
        ${ECHO} "@dir(opensearch,opensearch,0750) ${ETCDIR}/opensearch-observability" >> ${TMPPLIST}
        ${ECHO} "@dir(opensearch,opensearch,0750) ${ETCDIR}/opensearch-performance-analyzer" >> ${TMPPLIST}
        ${ECHO} "@dir(opensearch,opensearch,0750) ${ETCDIR}/opensearch-reports-scheduler" >> ${TMPPLIST}
        ${ECHO} "@dir(opensearch,opensearch,0750) ${ETCDIR}/opensearch-security" >> ${TMPPLIST}

should all be inside a check for the PLUGINS option

.if ${PORT_OPTIONS:MPLUGINS}
.endif

as these seem to be individual subdirs for the config of the plugins?
