+------------
+The driver currently depends on pyev for its core event loop. The pyev library
+depends on libev.  If you're on Linux, you should be able to install libev
+through a package manager.  For example, on Debian/Ubuntu:
+
+    .. code-block:: bash
+
+      $ sudo apt-get install libev-dev
