This can be worked around by replacing the libpng:1.2 dependeny by libpng:0 on net-misc/nxclient
yeah... changed it to =media-libs/libpng-1.2* to be stable-user friendly ;)
(In reply to comment #2) > yeah... changed it to =media-libs/libpng-1.2* to be stable-user friendly ;) Now it does not work for unstable users: Even if media-libs/libpng:1.2 is installed, it wants to downgrade media-libs/libpng-1.4.2 to media-libs/libpng-1.2.43-r2, apparently because portage wants to resolve into the same slot. I am not sure whether this is perhaps a portage-2.2_rc67 error, but I suppose that the dependency || ( media-libs/libpng:1.2 =media-libs/libpng-1.2* ) would fix the issue.
(In reply to comment #3) > Now it does not work for unstable users Just for the records: The recent reordering of libpng versions (fix of bug 319457) solved the issue for unstable user.
