Why do I need mysql for a python package?

Guys, I just tried to install your module, however it asks me for some mysql configuration.

    ERROR: Complete output from command python setup.py egg_info:

I don't have 'mysql' server on this computer, and also I would like to avoid installing another deamon on my computer.
I would like just your point of view. Thanks

Start by reproducing the installation and reviewing setup.py together with mysqlclient/setup_posix.py, especially the mysql_config lookup shown in the traceback. Trace why mysqlclient is required and determine whether the dependency or its installation guidance needs changing; done means the package's MySQL requirement is clearly explained or the unnecessary requirement is removed.
