I just downloaded ffmpeg and it appears to be missing the libavcodec.dylib.51.9.0 library: $ port contents ffmpeg Port ffmpeg contains: /opt/local/bin/ffmpeg /opt/local/bin/ffplay /opt/local/bin/ffserver /opt/local/include/ffmpeg/adler32.h /opt/local/include/ffmpeg/avcodec.h /opt/local/include/ffmpeg/avformat.h /opt/local/include/ffmpeg/avio.h /opt/local/include/ffmpeg/avutil.h /opt/local/include/ffmpeg/common.h /opt/local/include/ffmpeg/fifo.h /opt/local/include/ffmpeg/integer.h /opt/local/include/ffmpeg/intfloat_readwrite.h /opt/local/include/ffmpeg/log.h /opt/local/include/ffmpeg/mathematics.h /opt/local/include/ffmpeg/md5.h /opt/local/include/ffmpeg/opt.h /opt/local/include/ffmpeg/rational.h /opt/local/include/ffmpeg/rtp.h /opt/local/include/ffmpeg/rtsp.h /opt/local/include/ffmpeg/rtspcodes.h /opt/local/include/ffmpeg/swscale.h /opt/local/lib/libavcodec.a /opt/local/lib/libavformat.a /opt/local/lib/libavutil.a /opt/local/lib/pkgconfig/libavcodec.pc /opt/local/lib/pkgconfig/libavformat.pc /opt/local/lib/pkgconfig/libavutil.pc /opt/local/share/doc/ffmpeg/faq.html /opt/local/share/doc/ffmpeg/ffmpeg-doc.html /opt/local/share/doc/ffmpeg/ffmpeg_powerpc_performance_evaluation_howto.txt /opt/local/share/doc/ffmpeg/ffplay-doc.html /opt/local/share/doc/ffmpeg/ffserver-doc.html /opt/local/share/doc/ffmpeg/hooks.html /opt/local/share/doc/ffmpeg/optimization.txt /opt/local/share/doc/ffmpeg/soc.txt /opt/local/share/doc/ffmpeg/TODO /opt/local/share/man/man1/ffmpeg.1.gz /opt/local/share/man/man1/ffplay.1.gz /opt/local/share/man/man1/ffserver.1.gz A friend tells me I should be seeing this: /opt/local/lib/libavcodec.dylib -> libavcodec.dylib.51.9.0 /opt/local/lib/libavcodec.dylib.51.9.0 I'm trying to build transcode but it fails because this library is missing.
