This is a series of commands that sets up the terminal to run the program runCEA.sh in the c chell csh.

cd download
cd CEAexec
csh
setenv CLASSPATH path1:path2
setenv JDK_HOME /usr/jdk1.4
setenv PATH $JDK_HOME/bin:${PATH}:.

The next command is simply runCEA.sh

To get CEA working it was necessary to load the Xcode Tools 2.2.1 for Mac OS X 10.4.

Once these Mac Developer Tools were in place I downloaded g77-bin.tar.gz from 

http://hpc.sourceforge.net/

which is a site that contains a lot of free software for the mac.

The browser automatically unzips the compressed file to produce g77-bin.tar.gz

The g77 compiler is installed from the unix window using the command 

sudo tar -xvf g77-bin.tar -C /

This puts the files g77 and cpp into the directory

/usr/local/bin/ 

at the root level

Once these files have been installed they can be used to run the program runCEA.sh or if necessary recompile the programs enclosed with CEA according to Minna Chao's instructions
