I'll work on that, then.

/dev/epoll is the 'old' way. The new way that Linus approved (which went
in 2.5) is the system call. I'm not sure if libevent supports /dev/epoll.
On their website they say support for /dev/poll is planned, which is the
Solaris equivalent of /dev/epoll?

In any case, the headers should be updated in Gentoo for the new system
call numbers, so programs like libevent can build with all their
functionality, even if the current running kernel doesn't support it.
BTW, to test if memcached (rather, libevent) is using epoll:
# EVENT_SHOW_METHOD=1 memcached
