Python build FAILED (OS X 10.14.6 using python-build 20180424)

Hello.
When I install by bundled_installer, bundled_installer fails to install Python with the following error.

```

The following message is output to the logfile.

```
Python build finished successfully!
The necessary bits to build these optional modules were not found:
_dbm _gdbm _hashlib
_sqlite3 _ssl _uuid
nis ossaudiodev spwd
zlib
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

Could not build the ssl module!
Python requires an OpenSSL 1.0.2 or 1.1 compatible libssl with X509_VERIFY_PARAM_set1_host().
LibreSSL 2.6.4 and earlier do not provide the necessary APIs, https://github.com/libressl-portable/portable/issues/381
```

I want to know how to install python successfully.

Start with the bundled_installer path that invokes python-build and inspect the reported build log, especially the missing zlib and OpenSSL modules. Reproduce the installation on OS X 10.14.6; done means bundled_installer installs Python 3.7.2 successfully without the ensurepip or optional-module failures.
