I'd be happy to test and help improve things. From man emerge: --root-deps[=rdeps] If no argument is given then build-time dependencies of packages for ROOT are installed to ROOT instead of /. If the rdeps argument is given then discard all build-time dependencies of packages for ROOT. This option is only meaningful when used together with ROOT and it should not be enabled under normal circumstances! Does not affect EAPIs that support HDEPEND. Experimental EAPI 5-hdepend provides HDEPEND as a new means to adjust installation into "/" and ROOT. If ebuilds using EAPIs which do not support HDEPEND are built in the same emerge run as those using EAPIs which do support HDEPEND, this option affects only the former. crossdev wrappers set --root-deps=rdeps (read cross-emerge, this can be overriden), but be careful: If you only care about getting all the deps and maybe more then removing --root-deps might help you. However, when cross compiling you will likely run into broken deps since / and ROOT will not use the same keyword visibility.
