I am trying to set up ihaskell on EC2.  I start with the NixOs EC2 instance (from http://nixos.org/nixos/download.html) and then basically install the ihaskell package using nix-env -i ihaskell.  The installation runs fine but when I try to start the notebook with ihaskell notebook i get the following:

Updating IPython profile.

Exception: /root/.ipython/profile_haskell/ipython_config.py: openFile: does not exist (No such file or directory)

I poked around a bit and the root/.ipython/profile_haskell/ contains none of the expected profile files...  Could not find anything by googling around except the suggestion to run the ihaskell setup command which seems to have been discontinued

Can anyone suggest what I could try?

Thanks
