Sorry I was unclear.
It was the tweak in the config file.
PARAMETER sim_crho REAL 2 ->PARAMETER sim_crho REAL 2.
I had made all of the changes under the directory Simulation/SimulationMain/SodClump and then used ./setup to put the files in the object directory. The ./resetup wasn't relevant to my case but it is a handy thing to know.
Thanks John.

>>> Just a quick question first--had you compiled this code first in an object directory and you're trying to recompile after making these changes? If you add anything to the Config file you need to re-setup the code in this directory first, which you can do by issuing "./resetup" within the object directory, after which you can recompile.
