[Tutor] Total newbie question

[MR ZenWiz]

I'm trying to install python 4.6 on my Xubuntu 16.04 desktop, and I
keep getting scads of errors that culminate with this from make test:

running build
running build_ext
INFO: Can't locate Tcl/Tk libs and/or headers
warning: building with the bundled copy of libffi is deprecated on
this platform.  It will not be distributed with Python 3.7

Python build finished successfully!
The necessary bits to build these optional modules were not found:
_bz2                  _curses               _curses_panel
_dbm                  _gdbm                 _lzma
_sqlite3              _ssl                  _tkinter
readline              zlib
To find the necessary bits, look in setup.py in detect_modules() for
the module's name.

I'm not sure how to handle this, but the upshot is I can't run idle
(or idle3) on my system at all.

What's the trick to getting all of python set up so I can use it?  I
have not found a good guide for how to do this.

Thanks.
