    There are several build errors with Python 3.10, for example Python packages being installed in nested subdirectories ``local`` of what is supposed to be the target installation directory. We therefore strongly recommend using Python 3.8 or 3.9.
 
+3. Issues starting/finding ``ecflow_server`` due to a mismatch of hostnames
+   On some systems, ``ecflow_server`` gets confused by multiple hostnames, e.g. ``localhost`` and ``MYORG-L-12345``. The ``ecflow_start.sh`` script reports the hostname it wants to use. This name (or both) must be in ``/etc/hosts`` in the correct address line, often the loopback address (``127.0.0.1``).

 4. Errors such as ``Symbol not found: __cg_png_create_info_struct``
    Can happen when trying to use the raster plotting scripts in ``fv3-jedi-tools``. In that case, exporting ``DYLD_LIBRARY_PATH=/usr/lib/:$DYLD_LIBRARY_PATH`` can help. If ``git`` commands fail after this, you might need to verify where ``which git`` points to (Homebrew vs module) and unload the ``git`` module.
