--nogui option need, even if it is built with --with-x11 or something. for example, pintos project's automatic test phase, it needs bochs with --nogui option. And they're not exclusive option, so I can configure it with ./configure --with-x --with-x11 --with-term --with-nogui for all version. Reproducible: Always
seems to me that they are mutually exclusive...
All these configuration options are enabled in the latest ebuild if built with USE="X ncurses"
it looks to be passed now in 2.6.8
