Runtime error immediately after installation on Utah systems

Hi José,

calling for help in desperation after having tried everything I could think of to get target_selection up and running on Utah machines.

Problem - I am able to run target_selection (both 'main' and 'bhm_v05_3' branches), installed via git+python setup.py install on my local machine, communicating with the sdssdb via an ssh tunnel to Utah. However, repeating the installation process on the eboss.sdss.org machine, and running a trivial test post installation results in the following runtime error:

(py37) u6023218@eboss:/uufs/chpc.utah.edu/common/home/sdss10/sdss5/target/development/0.5.0$ target_selection --help

I have "pip install -U" updated to latest versions, all packages referred to within target_selection/setup.cfg, including sdssdb and sdsstools.

I expect I'm doing something trivially stupid, but cannot for the life of me work out what it is!

Any pointers?

Cheers

Tom

Start with target_selection/utils/init.py and xmatch.py, using the traceback as the entry point; inspect the installed sdss-target-selection 0.2.3 package against the branch being installed and the dependencies in setup.cfg. Reproduce target_selection --help on the Utah machine after installation. Done means the command imports successfully and --help runs without the Timer ImportError.
