When you built Twisted (through the setup.py script) it will build the
epoll reactor if it can find the /usr/include/sys/epoll.h header file.
So you might check if that is present on the system where you built
Twisted.  If not, you're probably missing some development packages.

On my Ubuntu feisty system the file comes as part of the libc6-dev
package.
