The zabbix_proxy binary from "net-mgmt/zabbix34-proxy" is built against libmysqlclient.so only, i.e. sqlite support is set to "off". It is my understanding that the zabbix_proxy binary is able to provide support for mysql and sqlite databases at the same time, at least the zabbix_proxy.conf states that. (DBName should be set to a full path to use sqlite over mysql) So it would be really great to have sqlite support in the zabbix-proxy package as this allows running zabbix proxies with just a little sqlite database instead of spinning up a full blown mysql server.
This port contains the following options that allows for customising which backend database should be used and depended on: MYSQL=on: MySQL database support PGSQL=off: PostgreSQL database support SQLITE=off: SQLite database support ORACLE=off: Oracle database support It appears this is also the case for: net-mgmt/zabbix22-proxy net-mgmt/zabbix3-proxy net-mgmt/zabbix32-proxy net-mgmt/zabbix4-proxy If you are strictly using packages, I would suggest using poudriere [1] to create a custom package repository, allowing you to customise port OPTIONS while continuing to use packages.
