Problem with config file "missing" in Ipython

System: Intel 64 bit /Fedora 23  Scientific flavor /KDE (latest updates 
auto installed )
 Sage Version 6.5, Release Date: 2015-02-17 
Note1 : Other packages installed previously installed include Jupyter and 
Spyder
Note 2 :Jupyter , Spyder load (but not checked for functionality) 

Versions loaded ( per console ) 
Python 2.7.10 (default, Sep  8 2015, 17:20:17) 
IPython 4.0.1 -- An enhanced Interactive Python.



Sage was down loaded Sage from Fedora package repository as root with *"dnf 
install sagemath"  *
No errors posted on install.( It was very large unpacked  ) 

Icon loaded in work space but fails to launch application ( console screen 
disappears after briefly displaying) 

Launching from console as 
sage 
sage -ipython
sage -notebook=ipython

All fail with error 

*Console Error* 
Traceback (most recent call last):
  File "/usr/lib64/sagemath/local/bin/sage-ipython", line 6, in <module>
    from sage.repl.interpreter import SageTerminalApp
  File "/usr/lib64/python2.7/site-packages/sage/repl/interpreter.py", line 
105, in <module>
    from IPython import Config
ImportError: cannot import name Config


Launching from console as -sage -notebook=sagenb does function and brings 
up 

*Error message from Sage notebook *
Traceback (most recent call last):
  File "/usr/lib/python2.7/site-packages/flask/app.py", line 1475, in

    rv = self.dispatch_request()

    return self.view_functions[rule.endpoint](**req.view_args)

    return f(*args, **kwds)
  File "/usr/lib64/sagemath/src/sagenb/flask_version/worksheet_listing.py", 
line 335, in upload_worksheet
    from sage.misc.all import tmp_filename, tmp_dir
  File "/usr/lib64/python2.7/site-packages/sage/misc/all.py", line 67, in 
<module>
    from log import log_html, log_dvi, log_text
  File "/usr/lib64/python2.7/site-packages/sage/misc/log.py", line 64, in 
<module>
    import sage.repl.interpreter as interpreter
  File "/usr/lib64/python2.7/site-packages/sage/repl/interpreter.py", line 
105, in <module>
    from IPython import Config
ImportError: cannot import name Config

So I am assuming a file directory conflict with previously installed  
Ipython and version packaged with the rpm at Fedora

I need a simple fix and don't want to attempt to reconcile( or break)  the 
other software installation
