In my ubuntu 12.04, the graphviz is not the latest version(2.29). I need some features available in the latest version of graphviz. I tried to install the graphviz version 2.29, which requires libgraphviz4(>=2.18). I anyhow installed libgraphviz4 and installed graphviz 2.29. For that I have to remove packages libcdt4 and libpathplan4.

Now whenever I try to generate graph, I get some problems: For e.g.:

dot -Kfdp -n -Tpng -o samplePOS.png forcePOS.dot

It says:

dot: error while loading shared libraries: libgvc.so.6: cannot open
shared object file: No such file or directory

neato -Tps -o sample_1.ps sourcedot.gv

It says:

neato: error while loading shared libraries: libgvc.so.6: cannot open
shared object file: No such file or directory

So, I am looking for some ways so that I can run graphviz 2.29 in my ubuntu 12.04.
