mlt indirectly depends on both ffmpeg and ffmpeg-devel

[billgriffiths@…]

Trying to install kdenlive on mac os 10.6.4 latest error involves activation of ffmpeg.
Error message suggests deactivating ffmpeg. Tried that followed by install.
Here is terminal session, followed by log file.

Basically the problem is that mlt depends specifically on ffmpeg-devel, but a couple of its deps (opencv via frei0r-plugins, and sox) pull in ffmpeg by default (but can also use ffmpeg-devel). If you activate ffmpeg-devel and then uninstall ffmpeg, all the deps should be considered satisfied by ffmpeg-devel. Listing ffmpeg-devel before frei0r-plugins in mlt's depends_lib might help avoid this in future.

How do you force those two or so dependencies to go with the devel instead. I tried deactivating and uninstalling ffmpeg after activating its devel and it prevents me from doing so. Should i try a force uninstall using -f?

I will make the portfile change suggested. However, I also wish to point out that once the 'ffmpeg' port is updated to the 0.6 release, I can return mlt to depending on either ffmpeg or ffmpeg-devel port.

This was fixed in r71720.
