I have successfully used pyenv to install python 3.7 on this system, where it is running great. I tried to install python 3.4.7 and I got these errors

Installing Python-3.4.7...
Traceback (most recent call last):

ERROR: The Python ssl extension was not compiled. Missing the OpenSSL lib?

Clearly the ncurses devel package is actually installed so, I am at a loss to figure this out.
