I gather that you've synced so if you run emerge -a1 '=readline-5*',
that should install the latest 5.2_p14 ebuild which is appropriately
slotted.
Note that the latest stable version of ghc (6.12.3-r2) doesn't depend on
the old version of readline anyway. The main issue was that your portage
tree was out of date. Now that has been dealt with, I think you just
need to upgrade as normal. You can uninstall the old instance of ghc
before allowing it to re-install, in case it still blocks.
Cheers,
