    Python 3.4.1

    This build of python is configured with --enable-loadable-sqlite-extensions and a --prefix, any other settings are default. This build does not include modules for lzma, Tkinter and dbm, but does include ssl, gdbm and sqlite. Adding the missing modules should not be very difficult but requires wrapping the external sources that these modules require inside galaxy. 

    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;
