ffmpeg won't build with avfilter variant

[dershow]

I am trying to install ffmpeg with the new +avfilter variant, but it gives errors (and warnings) when I try to install. I have tried uninstall and re-install and different combinations of other variants, all with no luck. If I don't do the avfilter variant then it does build and install fine.

I am using an Intel machine (MacBook Pro) running 10.5.2.

Here is my install and errors:

sudo port install ffmpeg +avfilter
