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.
