I've made a fresh deploy (cf push) of a Bluemix application developed under Python 2.7 under the updated Bluemix base platform. The deploy shows an error at the Python PIP mechanism, which is the default package installer. Apparently the type of error might be related to a missing install of the openssl-devel package at OS level (SSL support).
Error message: ValueError: unsupported hash type md5
Error message: ImportError: No module named 'pip._vendor.requests'

I am having the same issue when I use an older buildpack like https://github.com/cloudfoundry/cf-buildpack-python.git#v1.1.2
An important hint received from @chughts:
I suspect that it is the stack that is catching you out. I think that the supported stack on Bluemix is now cf_linuxfs2. You will need to use a build pack that supports this stack.
My fix:
A new deploy with the latest Python buildpack fixed the issue:
cf push myapp1 -m 64M -b "https://github.com/cloudfoundry/cf-buildpack-python.git#v1.5.1" -c "python server.py"
The crash message is solved. Thanks @chughts for your hint and support. Problem solved.
