The Python.framework installed at '/Library/Frameworks/Python.framework' should have a subdirectory structure similar to this:

Python.framework
|
|-Headers [symlink to 'Versions/Current/Headers']
|
|-Python [symlink to 'Versions/Current/Python']
|
|-Resources [symlink to 'Versions/Current/Resources']
|
|-Versions
| |
| |-2.7 [directory created by 2.7 installer]
| |
| |-3.5 [directory created by 3.5 installer]
| |
| |-3.6 [directory created by 3.6 installer]
| |
| ...
| |
| |- Current [symlink to last installed version, e.g. '3.6']

Current Python.framework installers create a 2.x/3.x directory and Headers+Python+Resources symlinks, but fail to create a 'Current' symlink. This breaks the top-level symlinks and causes importing the framework via NSBundle to fail.

Please fix the framework build and/or install script to create the missing symlink.

This is by design for Python 3 installs; Current *is* created for Python 2 installs for historical reasons. See the discussion in bpo-18117 why trying to use -framework Python is not a good idea unfortunately.
