Dear list,

I am trying to load the package Rgraphviz on Mac OS X 10.4.9, and R  
2.4.1 using bioC 1.9 and Graphviz 2.12  and am running into the  
following problem:

 > library(Rgraphviz)
Loading required package: graph
Loading required package: geneplotter
Loading required package: annotate
Loading required package: Biobase
Loading required package: tools

KernSmooth 2.22 installed

Error in dyn.load(x, as.logical(local), as.logical(now)) :
	unable to load shared library '/Users/danielk/Library/R/library/ 
Rgraphviz/libs/i386/Rgraphviz.so':
   dlopen(/Users/danielk/Library/R/library/Rgraphviz/libs/i386/ 
Rgraphviz.so, 6): Symbol not found: _agfstnode
   Referenced from: /Users/danielk/Library/R/library/Rgraphviz/libs/ 
i386/Rgraphviz.so
   Expected in: dynamic lookup
Error: .onLoad failed in 'loadNamespace' for 'Rgraphviz'
Error: package/namespace load failed for 'Rgraphviz'

I have seen this problem posted before on the list, with the answer  
to reinstalling the latest binary from bioC. I have tried this and it  
didn't work. I have also seen something about setting the system  
variable DYLD_LIBRARY_PATH, and I tried setting it in ~/.bashrc:
export DYLD_LIBRARY_PATH=/usr/local/graphviz-2.12/lib

The same error as above still occurs. Does anyone know how to solve  
this problem?
