Can't install PIL on lambda.

tried to be able to import 'time' , 'io' and 'PIL' by Chromeless.activate_library() method, but I realized even simple import of PIL fail somehow in this environment. saved in another branch and gave up so far about this problem

[ERROR] Runtime.ImportModuleError: Unable to import module 'lambda_function': cannot import name '_imaging' from 'PIL' (/var/task/PIL/__init__.py)
