To use the dynamic loading of behaviors, you need to set the following 
environment variable, in your .bashrc file for bash users, or in your
.cshrc file for tcsh users. Adjust accordingly if your moos-ivp-pavlab
tree is not directly in your home directory.

In Linux:
==========================================
For bash users:
export IVP_BEHAVIOR_DIRS=/home/your_username/moos-ivp-pavlab/lib

For tcsh users:
setenv IVP_BEHAVIOR_DIRS '/home/your_user_name/moos-ivp-pavlab/lib'


In OSX:
==========================================
For bash users:
export IVP_BEHAVIOR_DIRS=/Users/your_username/moos-ivp-pavlab/lib

For tcsh users:
setenv IVP_BEHAVIOR_DIRS '/Users/your_user_name/moos-ivp-pavlab/lib'
