 Ok. I built libevent2 and set these two envs, and it looks like it's
 finding libevent fine.

 > obfsproxy doesn't have a --with-libevent-dir switch in its configure
 script, and I think it's intentional, because the correct way of doing
 this is by using `pkg-config`. I'm not sure what `pkg-config` is exactly
 -- I think it's a package with some rules for each library that tells you
 where to find its objects and headers -- but that's what I remember Nick
 saying in IRC.
 > That said, we should add `pkg-config` to the to-apt-get-install-list.

 That's odd -- tor doesn't use pkg-config. I wonder if the "pkg-config vs
 --with-libevent-dir" discussion is worth a separate ticket so it doesn't
 get lost.

 > BTW, I've heard reports of people having problems with `ntohl` during
 `configure`, and I remember seeing something similar in an Ubuntu system
 some months ago. I believe it's caused by the script in `m4/winsocks.m4`,
 which was added by Zack, because ''ntohl and a bunch of related functions
 require a special library on Windows.''. Could this also cause problems in
 Linux? Unfortunately, I don't know autotools, and I won't be able to play
 with this for the next some days. Nick, any ideas?

 Correct, my ./configure now fails at
 {{{
 checking for library containing ntohl... no
 configure: error: could not find ntohl
 }}}
