The code in portaudio19-19+svn20071022/src/common/pa_ringbuffer.c
contains support for amd64:

#   elif defined( __i386__ ) || defined( __i486__ ) || defined( __i586__
) || defined( __i686__ ) || defined( __x86_64__ )
#      define PaUtil_FullMemoryBarrier()  asm volatile("mfence":::"memory")
#      define PaUtil_ReadMemoryBarrier()  asm volatile("lfence":::"memory")
#      define PaUtil_WriteMemoryBarrier() asm volatile("sfence":::"memory")

So there is no reason to disable jack support for amd64.

I modified debian/rules to enable jack for amd64, too.
With this modification, mixxx works with jack.
