I've only just got it to compile on my MacBook Pro. However, I'm  
getting a bus error from mythwelcome. I readily admit this may be due  
to some of the hacking I'm about to describe.

I installed all the prereqs using DarwinPorts. You have to build  
darwinports itself from source, to get an intel binary, then after  
that it works pretty smoothly.

I used these arguments to configure:

env QMAKESPEC=/opt/local/share/qt3/mkspecs/macx-g++ \
LD_LIBRARY_PATH=/opt/local/lib \
   ./configure --prefix=/opt/myth --arch=i686 \
             --disable-distcc \
             "--extra-cflags=-msse -msse2" \
             "--extra-cxxflags=-msse -msse2" \

QTDIR=/opt/local \

I also found it necessary to do a little hacking. This needs to be  
cleaned up, but it sort of brute forces through the errors:

patch to libs/libmythtv/videoout_quartz.cpp:
#ifdef HAVE_ALTIVEC // <--- add this
     if (gContext->GetNumSetting("MacYuvConversion", 1))
         data->yuvConverter = yuv2vuy_init_altivec();
#endif // <-- add this

patch to libs/libmythtv/yuv2rgb.h
#ifdef HAVE_ALTIVEC // <-- add this

#endif  // <-- add this

                               uint8_t * pu, uint8_t * pv,
                               int h_size, int v_size,
                               int vuy_stride, int y_stride, int  

#ifdef HAVE_ALTIVEC // <-- add this
vuy2yuv_fun vuy2yuv_init_altivec (void);
#endif // <-- add this

patch to libs/libavcodec/liba52/resample.c
//#ifdef ARCH_X86
//#include "resample_mmx.c"

void* a52_resample_init(uint32_t mm_accel,int flags,int chans){
void* tmp;
//#ifdef ARCH_X86
//    if(mm_accel&MM_ACCEL_X86_MMX){
//      tmp=a52_resample_MMX(flags,chans);

I seem to have missed the email that explains why we're sending this  
information, but just to pile on, here's the info from
