[R--gR] installing Rgraphviz on mac

[Alex Biedermann]

Dear gRaphical models members

I am not sure if I'd better address my question to the Mac Port SIG.
I am trying to get Rgraphviz running on a mac ppc vers. 10.4.11.
The installation process doesn't complete successfully.
Graphviz is already installed and should be
at /usr/local/graphviz-2.14 on my machine,
but it seems that when installing Rgraphviz, Graphviz
can't be found. Can I tell it so
manually? Or, do you see any other way to get
it running properly?

Thanks a lot in advance.

Alex
