Python build finished successfully!
The necessary bits to build these optional modules were not found:
_dbm                  _gdbm                 _ssl               
_uuid                                                          
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                
time

For lzma， download source package xz-5.2.4 (there might be problems if use other versions of xz) which in /home/tao/packages/xz-5.2.4.tar.gz, and unzip it by tar xzf xz-5.2.4.tar.gz.
