I'm testing an application that uses rgl (installed with apt-get install 
r-cran-rgl)
but fails, at least partly because that application uses a more current 
version.
There is also a mysterious error msg from Xlib:

Petal.Width) ~
+ Species, data=iris)

Error in ellipsoid(gmean, E, radius, col = last(col), label = "Error") :

Version 2.3.1 (2006-06-01)
i386-pc-linux-gnu

attached base packages:
[1] "methods"   "stats"     "graphics"  "grDevices" "utils"     "datasets"
[7] "base"

other attached packages:
      rgl       car
"0.64-13"   "1.2-0"

If I run example(rgl) alone, things sort of work (I get the volcano data 
displayed),
but I get the same Xlib: message:

 > example(rgl)

rgl> example(rgl.surface)
rgl.sr> data(volcano)
  ...
rgl.sr> rgl.clear()
Xlib:  extension "XFree86-DRI" missing on display ":0.0".

rgl.sr> rgl.surface(x, z, y, color = col)


I obtained the most recent source package for rgl and tried to install it
directly, but this fails.  Any idea what I can do?  How can I tell what X
component is being looked for?

Is this what I need?

Hi Michael.

I'm not very familiar with the rgl setup on *nix.  However, I can tell 
you that the configure script was built by autoconf, and the test that 
is failing is this one from configure.ac:

   AC_PATH_X
   if test x$no_x == xyes ; then
     AC_MSG_ERROR([X11 not found but required, configure aborted.])
   fi

Hopefully that means something to you, or to someone else on the list.

There is the usual option for you to supply your own path to X, via

X features:
   --x-includes=DIR    X include files are in DIR
   --x-libraries=DIR   X library files are in DIR

but I've no idea what would be appropriate for Debian, and I don't know 
what the "XFree86-DRI" extension is about.
