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 OpenMx/libs/i386/OpenMx.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
