Do as it says and deactivate port render

sudo port deactivate render

then try again.

You should also make sure that you have updated any outdated xorg-* 
ports as there have been a lot of changes in dependencies here
recently.

If you have port ffmpeg installed and activate you will want to 
deactivate that too as ffmpeg and ffmpeg-devel will want to install the 
same files so only one can be active at the same time.

To see what ffmpeg you have installed

sudo port installed ffmpeg
