[wplug] Odd X slowness

Well, seems like I tried every diagnostic except for the most
simple - running the program in question from the command line.
When running as the slow user, I get the following extra line on
the console:
  Loading required GL library /usr/X11R6/lib/libGL.so.1.2

So it appears that the software OpenGL rendering is the culprit
after all.  But what I can't understand is why this library is
being loaded for one user but not the others.  An "ldd
/usr/games/supertux" produces the same output for all users.  The
only libGL line there is "libGL.so.1 => /usr/X11R6/lib/libGL.so.1
(0x4012f000)".  Related-looking files in /usr/X11R6/lib/ are:
  /usr/X11R6/lib/libGL.so -> libGL.so.1.2*
  /usr/X11R6/lib/libGL.so.1 -> libGLwrapper.so.0.2.0*
  /usr/X11R6/lib/libGL.so.1.0*
  /usr/X11R6/lib/libGL.so.1.2*
  /usr/X11R6/lib/libGL.so.1.4.502*
  /usr/X11R6/lib/libGLU.so.1 -> libGLU.so.1.3.502*
  /usr/X11R6/lib/libGLU.so.1.3.502*
  /usr/X11R6/lib/libGLw.a
  /usr/X11R6/lib/libGLwrapper.so.0.2.0*
  /usr/X11R6/lib/libGLw.so -> libGLw.so.1.0*
  /usr/X11R6/lib/libGLw.so.1 -> libGLw.so.1.0*
  /usr/X11R6/lib/libGLw.so.1.0*

As you can see, libGL.so.1 does *not* point to libGL.so.1.2.
Anyone have any idea what is deciding that libGL.so.1.2 needs to
be loaded?
