Hello there,
I posted the following question on answers one month ago:
http://answers.ros.org/question/12552/findeigencmake-not-found-on-maverick-only

The answer I got is that the instructions on this page are wrong:
http://www.ros.org/wiki/eigen

Indeed, I had to add the FindEigen.cmake to my packages manually. The method
which is described does not seem to work (i.e. I get failures on the buildfarm).

Could someone double check the wiki and revert the modifications if needed?

Thanks,
