i have required libraries installed. followed http://www.paraview.org/wiki/paraview:build_and_install instructions installing paraview. ccmake $home/projects/paraview4 paraview-bin gave me error. help appreciated!

you've turned on paraview_enable_ffmpeg don't have ffmpeg development modules installed or locatable cmake. either installed ffmpeg or turn off paraview_enable_ffmpeg using ccmake or cmake-gui.

ffmpeg cmake paraview
