What happened to _tkinter.so?

I spent time today to investigate this.
If you install Python with Tkinter from source, _tkinter is built into
the Python executable and _tkinter.so is not generated *unless*
"shared" option is specified.
I found this by running python with '-v' option:
% python -v
>>> from Tkinter import *
import _tkinter # builtin <<<---
In the Module/Setup file:
# Uncommenting the following line tells makesetup that all following
# modules are to be built as shared libraries (see above for more
# detail; also note that *static* reverses this effect):
I tried to uncomment the line and I got successfully _tkinter.so under
This may be an issue for PyInstaller as it relys on _tkinter.so to
find the path to TCL/TK.
However, many Linux distribution includes _tkinter.so as many people
complained about missing _tkinter.so.
So, this is not really an issue unless you install Python by yourself.
