Hello everybody, I'm using net-misc/nxclient-2.1.0 on an amd64 machine since a while even though it lacks any amd64 keyword. It works perfectly for me so please consider keywording it ~amd64. It depends on sys-libs/lib-compat which also lacks any amd64 keywoard. I'm using lib-compat-1.4.1 here without problem. Thanks
nxclient is a 32bit binary-only package, so it needs some dependencies cleanups for amd64 (mostly emul-linux-* deps). nxclient-2.1.0.ebuild in the NX overlay has these updated dependencies, plus some fixes (not yet added to portage).
net-misc/nxclient-2.1.0-r1 is in CVS, including ~amd64 keyword and matching dependencies
