Without looking to closely at the output I guess it is because it doesn't find the Graphviz libraries. On my machine 
they are installed to a subdirectory of the standard library directory, eg. something like /usr/lib/graphviz instead of 
/usr/lib. You need to tell gcc to look in this place when searching for libraries. On Linux, this may be set by using 
the environmnet variable LD_LIBRARY_PATH. To be specific, I do
# export LD_LIBRARY_PATH=/usr/lib/graphviz
# R CMD INSTALL Rgraphviz_1.0.tar.gz
(both commands executed from the same shell).
