      Python 3.4.1. Configured with the default settings, using --prefix=$INSTALL_DIR.

      Python as of version 3.3 includes a built-in virtual environment manager. To create a python 3 virtual env, include the following actions in your tool_dependencies.xml:

      &lt;action type="set_environment_for_install"&gt;
        &lt;repository name="python3" owner="jankanis"&gt;
          &lt;package name="python3" version="3.4.1" /&gt;
        &lt;/repository&gt;
      &lt;/action&gt;
      &lt;action type="shell_command"&gt;
        # Unset any saved environment settings from parent virtual
        # environments, e.g. for python 2 or if Galaxy itself is running
        # from within a virtual environment.
        unset _OLD_VIRTUAL_PATH; unset _OLD_VIRTUAL_PYTHONHOME
        pyvenv {{\$MY_PACKAGE_NAME}}
        . {{\$MY_PACKAGE_NAME}}/bin/activate
        pip3 install {{\$PYTHON-PACKAGE}}
      &lt;/action&gt;
      &lt;action type="set_environment"&gt;
        &lt;environment_variable name="PYTHONPATH" action="prepend_to"&gt;\$INSTALL_DIR/lib/python3.4/site-packages&lt;/environment_variable&gt;
      &lt;/action&gt;
