Which deptree are you talking about? The --tree output of portage does not show you any USE flag conditionals. Additionally, if you disable the flag with FEATURES=test enabled, test phases will fail, so those packages will fail to install, i dont think, that this is the better option. -- Thomas Sachau Gentoo Linux Developer
