Trying to run ipython after installing via pip causes:
$ ipython
-bash: ipython: command not found
Do I need to add a directory to my path? The python installation guide doesn't mention it:
http://ipython.org/install.html
Everything seems to be installed as expected:
$ pip show ipython

I guess this error may have happened the first time around, as it still thinks it has been installed properly!
