No, it is part of the GNU Fortran installation. Anything you compile  
with a Fortran requires that you have that Fortran installed at run  
time, because Fortran uses its own run-time libraries (if the Fortran  
you compiled with used dynamic libraries). This implies that if you  
distribute your package you have to tell users to install the same  
Fortran you used to compile it.

However, unlike other unices Mac users don't necessarily have  
development tools installed, so on CRAN we make an effort to modify  
the binaries such that they work even without the tools they have been  
compiled with. There are several possible approaches, but since R  
itself already uses the same Fortran, we ship a copy of the Fortran  
libraries inside R and modify packages such that they use it instead  
of the one from dev tools (see below for details).

That is not sufficient to create a binary of your package, because it  
contains a configure script (this is unrelated to the above - see R- 
admin 2.6). What you want to use is something like this (assuming R  
2.10.1 Leopard build and Fortran from CRAN):

R --arch=i386 CMD INSTALL OpenMx_0.2.9-1147.tar.gz
R --arch=x86_64 CMD INSTALL --libs-only OpenMx_0.2.9-1147.tar.gz
R --arch=ppc CMD INSTALL --libs-only OpenMx_0.2.9-1147.tar.gz
cd /Library/Frameworks/R.framework/Versions/2.10/Resources/library

# fix the Fortran paths to point to R 2.10 instead
for lib in `ls OpenMx/libs/*/*.so`; do
   install_name_tool -change /usr/local/lib/libgfortran.2.dylib \
     /Library/Frameworks/R.framework/Versions/2.10/Resources/lib/ 
libgfortran.2.dylib \
    $lib
done

# change permissions for distribution
sudo chown -Rh root:admin OpenMx
sudo chmod -R g+w OpenMx

# pack it up
tar fvcz ~/OpenMx_0.2.9-1147.tgz OpenMx


You can check that you have the correct paths using otool -L:

ginaz:library$ otool -L OpenMx/libs/*/*.so

If you are dealing with only one R version, you can change the ID of  
your Fortran library instead of touching the package files:

install_name_tool -id \
    /Library/Frameworks/R.framework/Versions/2.10/Resources/lib/ 
libgfortran.2.dylib
   /usr/local/lib/libgfortran.2.0.0.dylib

Note, however, that this will lead to (possibly silent) errors if you  
forget to change it when switching to another R version, so I prefer  
to fix the package instead.

Cheers,
Simon
