I followed the instructions and everything went fine until the cmake stuff. Fedora Installation Guide

cmake .. -DCMAKE_INSTALL_PREFIX=/opt/ros/fuerte -DSETUPTOOLS_DEB_LAYOUT=OFF -- +++ catkin -- Could NOT find PY_em (missing: PY_EM) CMake Error at catkin/cmake/empy.cmake:29 (message): Unable to find either executable 'empy' or Python module 'em'... try
installing package 'python-empy' Call Stack (most recent call first):
catkin/cmake/all.cmake:51 (include)
catkin/CMakeLists.txt:12 (include)

any ideas?

It looks like you are missing the EmPy Python package. On Ubuntu that is installed as a Debian package dependency.

Maybe there is a corresponding Fedora 14 package. If so, I would use it.

Otherwise, try installing it with pip:

sudo pip install -U EmPy
