py3tool is in the root directory of the PyMVPA package. 

Did you add the PyMVPA root directory to the PYTHONPATH environmental variable?

For example, if PyMVPA is in /home/mike/git/PyMVPA, you could do

export PYTHONPATH=${PYTHONPATH}:/home/mike/git/PyMVPA

Also, if you add this line to .bash_profile (in your home directory), this will be executed automatically every time you open a new Terminal window
