Thanks for the response. However, this has opened another can of worms and I'm bowing to the expertise of this list to help

However, following your advice, I first attempted to reinstall kdm. This had been an update 6 days ago when all this started. The emerge bombed. Therefore, I fixed my package.keywords file so, the unstable version of libpng would not emerge and re-emerged libpng.

However, the actual revdep-rebuild bombs and I get told that there are no e-builds to satisfy PyQt:0. I admit that I have qt3support as a USE flag. Don't know if this is the issue and if I should remove it. Advice? Regards, Colleen
