xalf (unless you run it in mapping mode) operates by setting
LD_PRELOAD to point to a little dynamic object which overrides
XMapWindow(). The override function dlopen()s libX11 to find and call
the real XMapWindow() function. Unfortunately, this doesn't work when
the program was linked against an old version of the X libraries;
libxalflaunch finds the wrong version of the function. I don't think
there is any good way for libxalflaunch to determine what X library to
load, so I don't think there's a good solution.
