This worked great Bruce. Thank you. Althought this wouldn't
solve the problem for creating packages to distribute, it 
does indeed solve my needs and so I am very very grateful :
I can finally get on with building my app (after
over 24 hours complete downtime trying to solve this).
Am cc'ing the list because this deserves to to be in the 
archive and may prevent somebody else from wasting too
much time. 

Thanks again,

chas
