I am using R-1.8.0 (macos 10.2.8) and have a working version of ggobi
installed.  I am trying to install Rggobi and have had problems.  I have
followed the instructions in the INSTALL file included with Rggobi that
include:

-----------------INSTALL FILE EXCERPT-------------
e) R interface

Install R after downloading and following instructions from
  http://www.R-project.org

>From the ggobi web site, download Rggobi_0.51-0.tar.gz.

Set various system parameters:

% setenv R_HOME $HOME/R (where R got installed)
% setenv GGOBI_ROOT $HOME/ggobi   (or wherever ggobi lives)
% setenv R_LIBS $HOME/R/library


% su

Set a symbolic link to the ggobi library and the gtkext library in the
/usr/local/lib directory (the one above where R resides):

% ln -s $GGOBI_ROOT/lib/libggobi.so /usr/local/lib/.
% ln -s $GGOBI_ROOT/lib/libgtkext.so /usr/local/lib/.

Install the Rggobi library:

% R CMD INSTALL Rggobi_0.51-0.tar.gz

which will create a directory called Rggobi in the
/usr/local/lib/R/library directory.
----------- END INSTALL FILE EXCERPT ---------

The libraries are dynamic libraries, so the files are called *.dylib and I
made that modification to the above.  The partial output includes:

Any thoughts?
