evas_render_method_lookup() does check if the module exists or not
evas_render_method_list() has harcoded values according to what is passed
to configure, hence does not check if the modules really exist. This
function should be fixed, imho.
So does not rely on the results of evas_render_method_list(). If
evas_render_method_lookup() fails, then it certainly means that the
module is not compiled, or is disabled at configure time for some reason.
First check if the result of configure says that software x11 (xlib) is
available, then be sure that the module is compiled and installed
