Python file runs, but is not found. Er?

Symptoms: File is apparently being used:

File "/usr/lib/python2.7/dist-packages/salt/renderers/pyobjects.py", line 449, in render
  exec final_template in _globals, _locals
File "<string>", line 6, in <module>
File "/usr/lib/python2.7/dist-packages/salt/utils/pyobjects.py", line 293, in __getattr__
  raise AttributeError

Great. However when I go to /usr/lib/python2.7/dist-packages/salt/utils/pyobjects.py it isn't in that directory and none of its pyc's are there either:

ls /usr/lib/python2.7/dist-packages/salt/utils/py*
/usr/lib/python2.7/dist-packages/salt/utils/pydsl.py  /usr/lib/python2.7/dist-packages/salt/utils/pydsl.pyc

Why is this happening? What am I missing about this -- I have tried searching and found nothing useful yet.

Update if this is any use: 

$ python -v
>>> import salt.utils.pyobjects
# /usr/local/lib/python2.7/dist-packages/salt/utils/pyobjects.pyc matches /usr/local/lib/python2.7/dist-packages/salt/utils/pyobjects.py
import salt.utils.pyobjects # precompiled from /usr/local/lib/python2.7/dist-packages/salt/utils/pyobjects.pyc

The python -v verbose output you posted shows that the file is imported from a different location:

/usr/local/lib/python2.7/dist-packages/salt/utils/pyobjects.pyc
#    ^^^^^

but you are looking in:

ls /usr/lib/python2.7/dist-packages/salt/utils/py*
#      ^^^^

.pyc files store a filename in the bytecode, and the file must've been moved from /usr/lib to /usr/local/lib. So when a traceback is shown, the filename from the bytecode is still pointing to the old location.

You can force a re-compile (running with sudo or another means to gain write access) with:

python -m compileall -f /usr/local/lib/python2.7/dist-packages/salt

to produce .pyc files that store the new location.
