You should be using libevent's buildlink3.mk, but it looks like you did. It's possible that the pkgconfig file isn't getting included. Look in your work directory at the buildlink3 shadow tree. You will also find a bunch of log files about which files from which package were included. Basically, I mean to look at *everything* under work/ (including files starting with .) and try to understand them, at least for a minute each. Also, set PKG_DEBUG_LEVEL (to 1, 2, or maybe even 3) and save the log and look over it. Also, you may want to put your package in wip; I find it easier to look at things there than via email.
