To run the EMCOR Python Package you will need to download the following:

1) EMCOR-python-package.tar
(see here: http://www.slac.stanford.edu/grp/lcls/controls/downloads/emcor/emcor-python-package.tar )

2) Python 2.7.9 - Python Interpreter
(see here:  https://www.python.org/downloads/release/python-279)

3) Qt-4.8.5     - C Shared library (can grab from the Qt site)
(see here: https://download.qt.io/archive/qt/4.8/4.8.5)

4) PyQt4        - Python module providing an API for the Qt library.

You can get PyQt4 from the PyPI (aka pip) repository. To do a download only of the package, you can run:
pip install --download <DIR> PyQt4

(see here: https://pip.pypa.io/en/latest/user_guide/#installing-from-local-packages)

Be aware that PyQt4 won't run unless the python interpreter it's built against has been compiled with shared-lib enabled
(e.g., when building python from source, you'll need to add the --enable-shared option in the ./configure step)

After you download  PyQt4 you can run pip install and then perform a local install. Instructions are available on the site.
