sorry Hannes - not sure how that got sent to personal address...
You can try to build the internal ffmpeg with different optimization
options like this:
$ make
.... terminates with an error....
$ cd quicktime/ffmpeg
$ make clean
$ make CFLAGS='-O0 -g'
.... hopefully works...
$ cd ../.. && make
Try different optimization levels in CFLAGS.

Okay so I configure without any flags at all then when it breaks I move
to the ffmpeg directory, make clean and the make CFLAGS="-O0 -g". After
a second of building this produces an error:
gcc -DHAVE_CONFIG_H -I. -I. -I../../../.. -D_LARGEFILE_SOURCE
-D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 -DHAVE_MMX -DUSE_MMX

-DHAVE_AV_CONFIG_H -I./../.. -I../.. -O0 -g -MT fdct_mmx.lo -MD -MP -MF
.deps/fdct_mmx.Tpo -c fdct_mmx.c -o .libs/fdct_mmx.o/tmp/ccdU7310.s:

If I run make in the ffmpeg directory with no flags then it builds
successfully. Then when I cd ../.. && make I get the same exit as before:
/usr/bin/ld: ffmpeg/libavcodec/.libs/libavcodec.a(cputest.o): relocation

I will try some other CFLAGS but with my lack of skills in this area I
will need to be very lucky...
