That information is not too hard to find in the installation instructions. Here it is if you are using the tcsh shell:

echo 'set path = ( ~/abin $path )' >> ~/.cshrc

Add this line to your .bashrc file in your home directory if you are using the bash shell:

export PATH=~/abin:$PATH

Find out which shell you are currently using with

echo $SHELL

You can switch to tcsh temporarily by typing "tcsh".
