from what I see:

        config PACKAGE_libunbound_libevent
                bool "Build with expanded network resource (libevent) support."
                default y

so unless you had modified your config, this should work by default, this is not possible without making libunbound_libevent as a standalone package or I guess I could make libreswan-nolibunbound package variant

Yes, I opted it out in the configuration. You do not need to split packages; just make sure option is selected if user wants libreswan. For some reason I opted it out.. Can't remember why..

openwrt / packages
