 I'm attempting to build the x264 port using OS 10.6.6. I removed all of my
 ports and am trying to install from a fresh build. I always run into the
 following error:

 :info:build /usr/bin/gcc-4.2 -o x264 x264.o input/timecode.o input/yuv.o
 input/y4m.o output/raw.o output/matroska.o output/matroska_ebml.o
 output/flv.o output/flv_bytestream.o input/thread.o input/lavf.o libx264.a
 -L/opt/local/lib -arch x86_64 -arch x86_64 -lm -arch x86_64 -lpthread -s
 -L. -lavformat -lswscale -lavcodec -lavutil -lm -lz -lbz2 -lpthread
 :info:build ld: warning: option -s is obsolete and being ignored
 :info:build ld: library not found for -lavformat
 :info:build collect2: ld returned 1 exit status
 :info:build make: *** [x264] Error 1

 How can I get libavformat to be built?
