# Most of the plugins use automagic dependencies, i.e. the plugin will
# get built if the binary it uses is installed. For example, check_snmp
# will be built only if snmpget from net-analyzer/net-snmp[-minimal] is
# installed. End result: most of our runtime dependencies are required
# at build time as well.
