This is probably what happened: 1. You have ncurses and emul-linux libraries installed. Everything's good. 2. You come up with this genius idea: LDFLAGS="-lncurses " 3. You uninstalled emul-linux (including 32-bit ncurses). Now you need to rebuild ncurses BUT YOU'RE LINKING IT AGAINST ITSELF. This fails because you don't have 32-bit ncurses (may fail even if you did, not sure). 4. Since you're linking everything against ncurses everything 32-bit fails. Duh! You could've probably fixed it by just removing that LDFLAGS line and rebuilding ncurses. -- Fernando Rodriguez
