[BioC] Rgraphviz load problem

[Jane Fridlyand]

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
Password:
* Installing *source* 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 done

Thank you again
