Running on a mac

[LHMarshall]

The final issue with running on a mac is that it never seems to return on OK status, seems to always return 38... and with my current setup if there are no warnings or errors the user will be notified of this (if there are warnings or errors those get displayed instead).

However the great news is that these are the results from my Windows machine for the capercaillie data:

and these are from my mac - almost identical and the only differences come from R and not the MCDS optimisation.
