[BioC] error loading the Rgraphviz package

[yan zhou]

HI, All,

I'm running R 2.6 on MacOSX, I installed the "Rgraphviz" version  
1.16.0 with no trouble at all. But when I tried to load the library I  
got error message as below:

 > library(Rgraphviz)
Loading required package: graph
Error in dyn.load(file, ...) :
   unable to load shared library '/Library/Frameworks/R.framework/ 
Versions/2.6/Resources/library/Rgraphviz/libs/ppc/Rgraphviz.so':
   dlopen(/Library/Frameworks/R.framework/Versions/2.6/Resources/ 
library/Rgraphviz/libs/ppc/Rgraphviz.so, 6): Library not loaded: /usr/ 
local/lib/libgvc.3.dylib
   Referenced from: /Library/Frameworks/R.framework/Versions/2.6/ 
Resources/library/Rgraphviz/libs/ppc/Rgraphviz.so
   Reason: image not found
Error : .onLoad failed in 'loadNamespace' for 'Rgraphviz'
Error: package/namespace load failed for 'Rgraphviz'



Does anyone have any clue why is it?


thanks a lot.
