my emerge -u --deep world tells me it can't resolve dependencies cos readline-4.3-r4 requires >=bash-2.05b-r2 and all ebuilds satisfying this have been masked. I tried it with or without ACCEPT_KEYWORDS, but it doesn't make a difference. I also tried various emerge sync and emerge rsync s over the last 16 hours, to see if this was just a temporary inconsistency in the portage tree, but it looks like this one is here to stay.
sorry for that. I've updated the 1.2 profile to allow that bash version. Please resync in about 45 minutes to be safe and try again. Sorry for the inconvenience there.
