When try to install the Joe editor with "sudo port install joe" the compilation fails with "error: implicit declaration of function 'login_tty' is invalid in C99 " as the last error. The following are the relevant lines out of the build log:

:info:build tty.c:975:6: error: implicit declaration of function 'openpty' is invalid in C99 [-Werror,-Wimplicit-function-declaration]
:info:build         if (openpty(ptyfd, ttyfd, name, NULL, NULL) == 0) {

:info:build 2 errors generated.
:info:build make[3]: *** [tty.o] Error 1
:info:build make[3]: *** Waiting for unfinished jobs....
I can also send the whole build log if needed.
So long
