I know that the readline ebuild says to run revdep-rebuild, but is there any
reason it can't be slotted? After upgrading to readline-5 there's no reason that
things that are linked against /lib/libreadline.so.4 can't be left working.
No need to do such thing, that's what revdep-rebuild is for.
Why on earth would you make a user rebuild an entire system when a little
exertion to slot the library (like has been done for nearly every other library)
would improve the user experience, save time, and improve Gentoo?
Case in point - I'm travelling this week and speaking at conferences - like I
have the time or battery power to rebuild almost 150 packages while crossing
oceans - all because one little program (in this case ghc, as needed by darcs)
wanted a newer version of readline!?!
Sorry that you feel the way you do about this bug. I'm not going to reopen it,
but I am certainly going to refer others to it.
