[Ubuntu][Some problems met recently]

[1] Couldn't make x3270 because of "fatal error: X11/Intrinsic.h: No such file or directory"

sudo apt-get install apt-file
sudo apt-file update
apt-file search Intrinsic.h

X11/Intrinsic.h                     ->   libxt-dev
X11/Xaw/Command.h          ->   libxaw7-dev
