[Users] Problem with compiling Einstein Toolkit on Cray system

[L.S. Oswald]

Dear Erik

In general I've been using the commands at 
https://docs.einsteintoolkit.org/et-docs/Simplified_Tutorial_for_New_Users. 
I have tried configuring with the debian.cfg file and also attempted 
creating my own configuration file. Moving onto a different computer 
solved my MPI issue but produced a new error, which I've written about 
in my reply to Rahul. I'm afraid I don't know what type of computer I'm 
using now but I should be able to find out tomorrow.

Hopefully my other email gives an overview of my latest problem. I 
attach the full log of the output received when building the toolkit.

Many thanks for your help,

Lucy
