Hi there,

Just updated my system and try to re-build Emacs. I installed the
required libs by the output of 'ldd emacs' (attached).

The funny thing is Emacs isn't linked to libXt. But if
libXt/libXt-devel is not installed, the configure script won't be able
to detect the window_system.

I am wondering is libXt-devel a false requirement to build Emacs?
