See attached ebuild. The gnome use flag will filter out lxde components that are gnome libs dependent for the users who chose so. pcmanfm is being rewritten and *will* depend on gvfs and then will pull many gnome libs.

gvfs doesn't depend on any gnome libraries, given proper USE flag settings. And most USE flags enable connectivity to different kind of remote file protocols and similar, which is something LXDE users may want as well, depending what sort of file access needs they have.
Till the user can choose thanks to the use flags, it will be fine. For the moment, pcmanfm ebuild does not pull anything from gnome, then it's fine. I pulled lxde-meta on my system, then I'll monitor the dependencies/use flags requierements for it.
