Mart,
Thanks for that info - it was exactly what I was looking for. (Also
sorry I seem to have missed the slot 4 - I do see it now.) It all
makes good sense.
Minor mini-rant - unfortunately, gtk+:2 is not quite as totally gone as
we'd all like. I still have 10 packages on my box requiring it. A few
still need it only for building, and some are expecting upgrades to use
:3. I suppose the rest are soon for the history bin.
