The python_orocos_kdl package is a Python wrapper around the
orocos_kdl package, and should not need Eigen.  I believe those lines
in the CMakeList.txt should get removed.  You can file a ticket on
http://orocos.org/kdl.

The orocos_kdl package (which ships with Electric) needs Eigen3, and
does not work with Eigen2. The kdl pacakge (which ships with
Diamondback) only works with Eigen2.

Hope this helps,

Wim
