I'm glad to report that apart from all the -devels that I needed to install then remove GIMP2.6.x (sorry if the instruction was posted and I didn't see it), GIMP 2.7.2 is working well apart from setting in single-window mode at restart does not stick but that's OK... it's only a click away to detach and unify.
IMO GIMP have just pleased users of Photoshop while remaining faithful to its long-time users.
Thanks, Andy for the links and Sproggy for building the RPMs.
There are still warning boxes (easily closed but annoying that I have to fix but that shouldn't be a problem (I think).
