Bug#472574: jack support should be enabled for AMD64

[Frans Oliehoek]

I really do not now anything about this, but could Peter be right?
I have the problem that selecting jack in mixxx is not an option on
amd64 lenny. According to the ubuntu guys, see:

https://bugs.launchpad.net/ubuntu/+source/portaudio19/+bug/183011

, this has to do with portaudio and apparently they fixed it? (although
there is still one complaint about instability?)

(Or should I try to do the whole thing in a 32bit chroot?)

Thanks!
Frans
