"dot" is not required for normal VTK use.  The dependency stems from
setting "BUILD_DOCUMENTATION" to "ON", it is used for generating
inheritance and collaboration diagrams for the doxygen documentation,
so it does not interfere in any way with how VTK works.

Unfortunately, I do not know what is causing your problems.  It sounds
like there could be a problem with your OpenGL installation.  In most
GNU/Linux distributions, OpenGL libraries are installed along with the
graphics card drivers, which is either a part of the X11 installation
(using hardware-accelerated Mesa drivers) or through separate driver
packages (like those provided by ATI and nVidia).  Reinstalling these
drivers might help; like others have pointed out, there should be a
symlink called "libGLU.so".

If a reinstallation does not work, you could try to track down the problem by
- using "ldd" on executables to make sure that the correct OpenGL
libraries are used by the dynamic linker
- examine the results of "glxinfo" [1]
- running other OpenGL applications (glxgears [1], games, screensaver
using GL...), to check whether OpenGL works in general


HTH,
