OpenWRT joins the python2.7.9, result to report an error, lacks the module, but how to solve?

Python build finished, but the necessary bits to build these modules were not found:
_bsddb             _sqlite3           _tkinter        
bsddb185           bz2                dbm             
dl                 gdbm               imageop         
sunaudiodev                                           
To find the necessary bits, look in setup.py in detect_modules() for the module"s name.
