Now that we are explicit about what python version we intend to use for dib we can have package installs optionally install packages depending on this. Add a new dib_python_version that matches on the DIB_PYTHON_VERSION string set by dib-python. Co-Authored-By: Adam Harwell <flux.adam@gmail.com> Change-Id: I70659aab7d12924bdb9bc0489a7f02d5fd0dbb39
