> Great, a person trying 64bit CPU for audio! I have lots of questions. > First, what do you mean by "not masked for AMD64". Is that a compile > flag in some apps? its packages masked via the portage profile. gentoo has a few safeguards against the system being 'too' bleeding-edge. once its marked as working and tested a package is unmasked by adding to the KEYWORDS of its ebuild, usually for ~arch first, then arch. none of the audio apps you mention below are masked, at least not for ~amd64. give them a go.. as necessary you can override by echoing the name to a file in /etc/portage if noone got around to testing it.. > had to build, and your experiences/problems with them?
