[R] about the possible errors in Rgraphviz Package

[Gabor Grothendieck]

I have also installed numerous different versions of
Rgraphviz/graphviz  in an attempt to get it to work and so far have
been unsuccessful in getting it to install as well.  Some time ago I
used it successfully but have had no luck with recent versions.  Its
too bad there are so many installation problems since its otherwise a
very useful package.
