I suspect that something else has dragged in the gui part of glc - wxwindows IIRC. > > A different example - gnupg: > > [ebuild R ] app-crypt/gnupg-1.4.2-r3 USE="X caps* ecc* idea* nls > readline static* usb zlib -bzip2* -curl* -ldap -smartcard" 21 kB > > As you can see here, gnupg is built with the flag X set. > What has been enabled with that? > A global use flag like X has different effects on different packages. Ususally it affects whether or not an X gui is built. However the only wat to really tell is to read the ebuild. In this case: "RDEPEND="!static? ( ${COMMON_DEPEND} X? ( || ( media-gfx/xloadimage media-gfx/xli ) ) ) selinux? ( sec-policy/selinux-gnupg )"" This indicates that if the X flag is enabled, there will be a dependency on either media-glx/xloadimage or media-gfx/xli "econf \ [snip] $(use_enable X photo-viewers) \ [snip] ${myconf} || die" This indicates that something called photo-viewers is enabled in gnupg if the X flag is present. What this does, i don't know (or care) and will leave it to you to discover. > Also quite a number of libraries support X, like > > [I--] [ ] gnome-base/libbonoboui-2.10.1-r1 (0) > [I--] [ ] gnome-base/libgnomecanvas-2.12.0 (0) > [I--] [ ] gnome-base/libgtop-2.12.2 (2) > [I--] [ ] gnome-base/libglade-0.17-r6 (0) > > What do all of these do with X?
