Now I get the following error, I think somewhat later on:

gcc -dynamiclib -Wl,-single_module -Wl,-install_name,/usr/local/lib/ 
libswscale.dylib,-current_version,0.5.1,-compatibility_version,0 -Wl,- 
read_only_relocs,suppress -L"/Users/orcein/src/ffmpeg"/libavutil -Wl,- 
dynamic,-search_paths_first  -o libswscale.0.dylib rgb2rgb.o swscale.o  
yuv2rgb.o -lavutil -lz -lm -lfaac -lfaad -lmp3lame -lm
ld: absolute addressing (perhaps -mdynamic-no-pic) used in  
_rgb24tobgr24_MMX from rgb2rgb.o not allowed in slidable image
collect2: ld returned 1 exit status
make[1]: *** [libswscale.0.dylib] Error 1
make: *** [lib] Error 2
