Hello,
Quick description of the problem:
Mac OS X 10.2 doesn't have dlsym/dlopen/dlclose as part of the
standard libraries. It means if you compile ffmpeg on 10.4, the
binary will work fine on 10.4 but due to the dlsym call in a52dec.c,
it will not work on 10.2 because of the dlsym undefined symbol.
This patch avoid this dependency when it's not required, meaning the
same binary will work on 10.2 -> 10.4 even if liba52 is enabled.
Patrice
