I've looked deeper into the problem and it turned out that
the unresolved references in liba52-devel.so are coming from
FFMpeg-2005112800/libavcodec/liba52/imdct.c where the code reads:

    #ifdef LIBA52_DJBFFT
    if (mm_accel & MM_ACCEL_DJBFFT) {
        ifft128 = (void (*) (complex_t *)) fftc4_un128;
        ifft64 = (void (*) (complex_t *)) fftc4_un64;
    } else
    #endif

and after re-building the port /usr/ports/audio/liba52-devel with
'make WITHOUT_DJBFFT=yes install' the problem in the the port
/usr/ports/multimedia/ogle went away and ogle installs fine.
