Hello all, I would like to know if there is a good (perhaps best) approach in resolving issues with packages with circular build dependencies. Libav has various circular build dependencies including. libav -> opencv -> libav libav -> x264 -> libav libav -> x264 -> gpac -> libav I found some mention of this issue at [1]. This however doesn't offer any clear solution. 1. http://wiki.debian.org/DebianBootstrap ~ Andres
