Hi all, I am attempting to install the NI driver over unstable.  I have
followed the instructions carefully and have managed to squash a number of
bugs along the way, but I can't find my way past this one.

I have everything ready as per the instructions and run the rosmake ni
--rosdep-install and it goes fine until it reaches this

error: Eigen/Core: No such file or directory

It cannot seem to find Eigen/core yet I know I have it installed and can see
it is lcoated in /usr/include/eigen2/Eigen.

How can I get rosmake to see my Eigen/core?  Or is there another problem I
need to address?

thanks much
Brian
