        pg_config is required to build psycopg2 from source.  Please add the directory
        containing pg_config to the $PATH or specify the full executable path with the
        option:
        
            python setup.py build_ext --pg-config /path/to/pg_config build ...
        
        or with the pg_config option in 'setup.cfg'.
        
        If you prefer to avoid building psycopg2 from source, please install the PyPI
        'psycopg2-binary' package instead.
        
        For further information please check the 'doc/src/install.rst' file (also at
        <http://initd.org/psycopg/docs/install.html>).
