http://iweb.dl.sourceforge.net/project/levent/libevent/libevent-2.0/libevent-2.0.18-stable.tar.gz returns 404.

When I execute configure and then make in release/toolkits/graph_analytics, I get as follows.

(Fedora23 and RHEL7, same error)

I was having the same issue on Ubuntu 14.04, and amaya382's url change fixed it.
