But that will overwrite my current .rpmmacros file, which I need for the 
'normal' rpm build structure that I use.
Isn't there a more non-destructive way? :) Preferably it should work on 
other users systems too. I think it's bad to make assumptions on there 
.rpmmacros file....

Thanks for your reply,
