Missing Bits for Some Modules During Installation

I install Python 2.7.9 from compiling its source on 64-bit Ubuntu 14.04. Running make seems without error, but it also says that

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

1. If I don't need the modules, can I safely ignore those modules and their missing bits for now? If I need the modules in the future, can I install them then?

2. If I need to install them, how shall I install the missing bits for the modules and then install the modules?

   • It says to look in detect_modules()(I extract the function from setup.py into the linked file) in setup.py for the modules, but I am not sure how to do that for each module individually?

   • Are "the missing bits" some development libraries (not just shared libraries, but also having source code)? In Synaptic package manager, I am only guessing which library to install.

   For example,

   for _ssl module in python, shall I install libssl-dev in Ubuntu?

   for _bsddb and for bsddb185, I don't know what to install. In synaptic, python-bsddb3 is already installed, and I don't find libbsddb3-dev or libbsddb3 but I find python-bsddb3-dbg. After installing python-bsddb3-dbg, make still says the bits for _bsddband forbsddb185` not found.

   for dl, I found that in detect_modules(), it seems to require dlfcn.h, which seems to be part of POSIX. Since Linux is POSIX compatible, I was buffled by that Ubuntu has missing bits of dl.

   For dbm and gdbm, I find libgdbm-dev in synaptic, but no libdbm or libdbm-dev but only libdbm-ocaml, libdbm-ocaml-dev, libdbm-deep-perl. What shall I install then (especially for dbm)?

   For sunaudiodev, I find from detect_modules(), that it seems to be a SunOS specific module. But why I need it on Ubuntu then? Thanks.

   For imageop, detect_modules mentiones imageop.c, but I don't know how to find it to install either.

   For _tkinter, I have installed python-tk and python-tk-dbg, but make still says its bits not found.

After install some development libraries, now make reports bits of the following modules not found:

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