Rgraphviz install issues

Hi -

R1.9.1; OSX 10.3.5; Dev Tools etc install.

I have installed, via darwinports, graphviz (v1.16) running in x11 (I  
also have the standalone aqua app...) Having done that, I have tried to  
install RGraphviz from the Bioconductor suite via the x11 route to R,  
as Rgraphviz needs graphviz in the x11 environment (I think).

First, I used the Bioconductor script

getBioC("graph")
which installed everthing successfully except RGraphviz and Guuid....

Assuming that the build of RGraphviz would require the library path for  
graphviz installed by darwinports, I tried this previously posted   
remedy  to install RGraphviz

dyn092203:~ apb$ export LD_LIBRARY_PATH=/opt/local/lib/graphviz
dyn092203:~ apb$ sudo R CMD INSTALL /Users/apb/Rgraphviz_1.4.0.tar.gz

ERROR: compilation failed for package 'Rgraphviz'
** Removing

Clearly, something else is missing in my effort..... Any advice would  
be appreciated.
Cheers
