Getting epoll working...?

[Brad Fitzpatrick]

You're confusing kernel-space and user-space headers.

You need the libc headers to build libevent.

There are no patches you need for libevent.  Just grab libevent-0.7.

The patches you need are for the kernel.  (but get the -lt, level
triggered, ones...)
