*** WARNING: renaming "_asyncio" since importing it failed: No module named '_socket'

Python build finished successfully!
The necessary bits to build these optional modules were not found:
_gdbm                 _lzma                 _sqlite3
_tkinter              readline
To find the necessary bits, look in setup.py in detect_modules() for the module's name.


The following modules found by detect_modules() in setup.py, have been
built by the Makefile instead, as configured by the Setup files:
_abc                  atexit                pwd

Following modules built successfully but were removed because they could not be imported:
