Sorry, I haven’t followed the whole thread but the part about ‘port installed’ caught my eye.  On my system:

$ port installed python27
The following ports are currently installed:
  python27 @2.7.10_2
  python27 @2.7.10_3
  python27 @2.7.11_0
  python27 @2.7.12_1 (active)

I have four versions of python27 installed but (sensibly) only one is active.  I interpret the output from your system to mean that you had python27 installed and active but now it is not active.  Probably because of a command like ‘sudo port deactivate python27 @2.7.12_1’.

You should be able to get your python back with ‘sudo port activate python27 @2.7.11_2’.
