wrong version off gcc in my sytem for a python build

I am trying to install a software package in my linux environment in a local directory . The package requires gcc version 4.9 or later and python 3.5 or later as . I have python 3.7 on my environment, however only have gcc v 4.8.5 on my environment.

When I run my setup.py script, it wont work because I dont have the current compiler version. What is ht best option to go about this install? Note that I cannot install a higher version of GCC on my environment. The best I could do is a local install that does not mess with the GCC 4.8.5 environment.
