Jeff hit the nail on the head with that one. I've replied to him personally 
and thanked him. What I had done was inadvertently run the make -f before I 
had edited the Setup.in file. I then edited the file as I should have and 
re-ran make -f without realising I had to delete the file called "Setup". 
Ignorance is a curse. Anyway, this little tip will no doubt help someone 
else in the future.
