providing an ebuild patch for dgen-sdl
Created attachment 78848 [details, diff] dgen-sdl-1.23.ebuild virtual/x11 is not really required, not used at link time (will be included by SDL in case, no include for X11 done. Maybe configure will break without it ? But even in case, my guess is that virtual/opengl or libSDL will take care of it
Fixed in CVS... The configure script looks for xmkmf, which comes from x11-misc/imake if compiled with --with-x, so I added it.
