Just to be clear....  You want me to run

$ ./configure
$ make
$ gcc -Llibavcodec -Llibavdevice -Llibavfilter -Llibavformat 
-Llibavresample -Llibavutil -Llibpostproc -Llibswscale -Llibswresample 
-Wl,-dynamic,-search_paths_first  -o ffmpeg_g ffmpeg_opt.o 
ffmpeg_filter.o ffmpeg.o cmdutils.o  -lavdevice -lavfilter -lavformat 
-lavcodec -lswresample -lswscale -lavutil -L/opt/local/lib -lSDLmain 
-Wl,-framework,AppKit -lSDL -Wl,-framework,Cocoa -lm -liconv -lbz2 -lz 

and then try moving the -liconv flag to just before -L/opt/local/lib flag.
RIght?

Here is the out from the first set of commands:

Undefined symbols:
  "_iconv_close", referenced from:
      _avcodec_decode_subtitle2 in libavcodec.a(utils.o)
  "_iconv", referenced from:
      _avcodec_decode_subtitle2 in libavcodec.a(utils.o)
      _avcodec_decode_subtitle2 in libavcodec.a(utils.o)
  "_iconv_open", referenced from:
      _avcodec_decode_subtitle2 in libavcodec.a(utils.o)
ld: symbol(s) not found
collect2: ld returned 1 exit status


Here is the output with -liconv moved to just before -L/opt/local/lib:

Undefined symbols:
  "_iconv_close", referenced from:
      _avcodec_decode_subtitle2 in libavcodec.a(utils.o)
  "_iconv", referenced from:

      _avcodec_decode_subtitle2 in libavcodec.a(utils.o)

Thanks for helping me and I certainly don't mind helping you out.  Any other commands you want to test out I'd be happy to run them.
