No, you are wrong. I just tested this with SDL and
used the fatbuild.sh ppc part. I am on a PPC Mac with the latest
XCode Tools and Updates :

c0a80121:/tmp/SDL-1.2/build/ppc/build/.libs wizard$ otool -L libSDL.dylib
libSDL.dylib:
        /usr/local/lib/libSDL-1.2.0.dylib (compatibility version 12.0.0,
current version 12.1.0)

I hope there is any way to do the checking.
