Build adapted ffmpeg and jffmpeg shared libraries on MAC OS X x86(repost)

We need someone to get our version of ffmpeg and jffmpeg build on mac os x x86 32 bit and 64 bit. The libraries compiles and runs currently on windows, linux and mac os x ppc. Unfortunately I don't' get it build on mac os x x86. There are serveral errors during build. Attached you will find the zip-file which includes the source and also the build-log, so you can see what is the problem. The ffmpeg version we adopted is 0.4.9. We made some changes to get the h.263+ codec version. Is it possible to build libraries which work on both architectures x86 and ppc? If yes this it what we want. The deliverables must include the adjusted build scripts and you must show that ffmpeg and jffmpeg get build on our mac (via ssh). We will integrate the libraries in our video conferencing solution and test if it work's. If there are any error's you should help to solve them.
