^^^ Bacon Saver, thank you.

Nice!

Wow, I guess I can do that in a Lamba function too says Stack Overflow... Assumes the function is in a VPC with internet access and no idea if it needs a `/tmp` provisioned, but wasn't aware of this harry pottery.
 

import os
import sys
import subprocess

# pip install custom package to /tmp/ and add to path
subprocess.call('pip install https://github.com/intersystems/quickstarts-python/raw/master/Solutions/nativeAPI_wheel/irisnative-1.0.0-cp34-abi3-linux_x86_64.whl -t /tmp/ --no-cache-dir'.split(), stdout=subprocess.DEVNULL, stderr=subprocess.DEVNULL)
sys.path.insert(1, '/tmp/')

fixed, thank you!
