Optional circular dependency between multimedia/ffmpeg and audio/chromaprint

[Luca Pizzamiglio]

Today I discovered a circular dependency:

if multimedia/ffmpeg has the chromaprint option enabled, then it needs
audio/chromaprint
audio/chromaprint always needs multimedia/ffmpeg

Using portmaster, I was unable to update both of them.
At the moment, I remove the option in multimedia/ffmpeg, but I don't a
better solution.

Best regards,
Luca
