Emulator

dolphin wont finish compiling on 12.04

i get this error at %100:

./VideoCommon/libvideocommon.a(AVIDump.cpp.o): In function AVIDump::AddFrame(unsigned char*, int, int)': AVIDump.cpp:(.text+0xef): undefined reference to av_rescale_q(long, AVRational, AVRational)'
collect2: ld returned 1 exit status
make[2]: *** [Binaries/dolphin-emu] Error 1
make[1]: *** [Source/Core/DolphinWX/CMakeFiles/dolphin-emu.dir/all] Error 2
make: *** [all] Error 2

i saw this http://code.google.com/p/dolphin-emu/issues/detail?id=5266#c5 which claims to have fixed it but i can not find the patch they are mentioned, also i would think the problem would be gone almost a month after the patch was submitted.

please help me.
