 I have compiled static libraries for ffmpeg with --enable-pic.  Adding
 -Wl,-Bdynamic did not help.

 That would indicate that you do not have the same problem, but ...

 > {{{
 > g++ -fPIC -L/tools/shed/opensource/ffmpeg/1.0.1/payload/lib64
 -L../../lib -shared audio.o lqt_ffmpeg.o params.o video.o -o lqt_ffmpeg.so
 -Wl,-Bdynamic -lquicktime -lavformat -lavcodec -lswscale -lavutil -Wl
 > /usr/bin/ld:
 relocation R_X86_64_PC32 against `ff_h264_cabac_tables' can not be used
 when making a shared object; recompile with -fPIC
 > /usr/bin/ld: final link failed: Bad value
 > collect2: ld returned 1 exit status
 > make: *** [lqt_ffmpeg.so] Error 1
 > }}}

 ... please add the output if you add -Wl,-Bsymbolic to the command.
