Here's the specific config error: gcc: /Users/anarkhos/Desktop/uae/e-uae-0.8.27/src/od-macosx/lib/SDLMain.o: No such file or directory OK, so sdl-config assumes this object file already exists. When should it have been made? I don't think in the main configure script, so perhaps in sdl-config? I don't see it being compiled in any of the scripts.
