Fixed bug #167 The configure script parses the value of $X_LIBS when looking at the --enable-x11-shared, which is getting set on Ubuntu 5.10 to "-L/usr/X11R6/lib" ... however, Ubuntu stores all the Xlib stuff in /usr/lib. The end result in SDL is that the dynamic X11 stuff gets disabled by default, unless you override like this: ./configure --x-libraries=/usr/lib
