I sincerely hope that Gentoo is not that broken. Implementing this
misfeature would require patching the Python interpreter.  By default
Python looks for modules in the "site-packages" directory, with a self
descriptive name.  Where else would you like to install NTPSec python
modules?

Delivering a 1.0 release that requires fiddling with PYTHONPATH to use
the application would make the project look like it is run by amateurs.
I think that is not the impression you want to give.
