Seems to placed there during upgrade from squeeze/pre-multiarch. My new
wheezy machines don't have it. My laptop does.

Sure, unless you're using the "just take the defaults" option. Which
Debian's libev-perl does, and thus doesn't compile in epoll support.

I've got my own automatic build stuff to upgrade/workaround Debian build
bugs. The EV_EPOLL variable was useful there, otherwise I probably would
have had to patch something.
