I am trying to install Rgraphviz under Mac OS X Tiger (10.4.2). I am using
the latest R (2.2) and Rgraphviz 1.8 . I downloaded and successfully
installed what i think is the most current graphviz dmg for mac (1.10.dmg).
It installed in /usr/local/lib/graphviz. I added thje fowllowing to .bashrc:

export LD_LIBRARY_PATH=/usr/local/lib/graphviz

Now, i am getting the follwoing error when installing and loading from
within R: the package seems to install but not load

> getBioC("Rgraphviz")

Running getBioC version 0.8  with R version  2.2.0 

Running biocinstall version 1.1  with R version  2.2.0

I also tried to install from the local file using R CMD INSTALL but get the
follwoing error which i am not sure how to remedy:

sparky$ sudo R CMD INSTALL Rgraphviz
* Installing *source* package 'Rgraphviz' ...
checking for graphviz... checking for dotneato-config...
configure: error: please specify a valid path to 'dotneato-config' version
>= 1.12 using --with-graphviz=DIR
ERROR: configuration failed for package 'Rgraphviz'
** Removing
** Restoring previous

I appreciate the advice. I noticed a lot of people were having issue with
installation and I looked thru the mailing list but most of the solutions
amounted to installing graphviz and exporting path  both of which I have

Thank you again
