This is a problem with the way we produce our tarballs (.tgz packages). 
I assume you downloaded the tarballs for your platform.
Unfortunately, the missing listut file is in the eclipse_misc tarball,
and is not in the eclipse_basic tarball. So you need to download the 
eclipse_misc tarball (if you are downloading from Sourceforge, you need 
to go to the "Common Files" packages, and find the "doc_contrib sources" 
for the ECLiPSe version you are using). Sorry about this mistake, we 
will correct it.

Your problem may indeed be connected to the problem with java_vc, but 
another issue may be the graphviz you are using: the visualisation code 
was developed sometime ago, and the graphviz used is now quite old. I 
don't know if the code will work with newer versions of graphviz -- when 
you say graphviz is properly installed, is this the version distributed 
with ECLiPSe?  If not, that might be an additional issue.
