HUH.
- after numerous attempts I managed to download get-pip.py
- after first run get-pip complained it cannot find zlib (not compiled during ./configure; make)
- killed zlib problem by yum install zlib-devel, re-config, re-make, no error on zlib
- got into issue of ssl
[vagrant@localhost pip]$ python2.7 get-pip.py
pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.

Hi @ljgww!
Could you tell me what's the output of doing python -c "import ssl; print(ssl.OPENSSL_VERSION)", using your custom built python?

I managed to resolve the issue by downloading and compiling OpenSSL libraries from source.
Compiling SSL got standard OpenSSL library in place where compiling of Python is looking (this part effectively included SSL in Python compilation that was skipped before since make could not find standard SSL on Oracle Linux)
After re-compiling Python make did get SSL functional in python, and therefore could finally do PIP. Will give more details later to see if this is valid procedure.

Steps that fixed the problem with SSL compiling into Python and consequent get-pip failure because of lack of SSL support in Python.
- download openssl-1.1.0f (tar.gz shall do the trick) from: https://www.openssl.org/source/
- unpack SSL source in folder
- go to folder
execute (for SSL to compile and install)
./Configure
make
sudo make installFinally - redo the Python compilation (configure, make, make install - repeat compiling proces for Python), observe that ssl library now compiles into Python as it appears in standard place where Python compiling procedure is looking for,
Test new python: python2.7 get-pip.py - latest pip shall install and work as it should.

Running ./Configure to install ssh (step 4) above made me Nuts, it was showing errors related perl modules and so on.
./config --prefix="
And had to copy Edit and Copy Modules/Setup.dist as described in https://stackoverflow.com/questions/5937337/building-python-with-ssl-support-in-non-standard-location?utm_medium=organic&utm_source=google_rich_qa&utm_campaign=google_rich_qa
However thanks a lot!

how to re-configure and re-make python in the fifth step that you mentioned ?

Essentially ... Repeat step 4 once more (but now you shall have openssl installed, correct?)
(Edit: i fixed my original recipe to be more clear what compilation is in question)
Essentially if you do not have SSL in place first compiling of python will not include SSL.
However if you do compile and install SSL
then python will recognize SSL being in place and will include it.
Note that as observed in newer versions of 2.7 there may be SSL provided by python itself which may (or may not) become preferential library used.

import ssl in python shell to test

With newer versions of python I discovered that there is a set of options that one can pass to python compiling/configuring but I did not find a good reference what can be used. For example 2.7.15 comes with python SSL library (optionally)
However above mentioned:
./Configure --prefix=xxx
shall be some of options of target location where installation will place compiled python. Read somewhere you can get them with:
./Configure --help
as to prefix typical (and default) prefix shall be /usr/local (this means when doing install python exec will appear as /usr/local/bin/pythonx.x
Be careful when using --prefix=/usr as you may overwrite sytem python on some linuxes (I ruined once and took me days to recover /usr will translate to /usr/bin/python....)
I have no idea what would happen on --prefix='' (essentially set to nothing). I can expect two outcomes: 1. installing default (/usr/local) or maybe installing in current folder (essentially not installing). Would like to hear what are experiences with this.
since here PIP in question observe Configure option:
--with(out)-ensurepip=[=OPTION]
"install" or "upgrade" using bundled pip, default is
"no"
