It could happen if the tinfo flag is removed (perhaps as an attempt to build 
one of the many broken packages). If the tinfo library is not preserved 
everything that linked against it stops working. That's one of the many 
problems with the current approach to this use flag (patching the multitude of 
broken packages). I patched my ncurses ebuild to build and install both a full 
ncurses along with a tinfo library, that causes the most packages to link 
against curses only so no rebuild is necessary after removing the use flag, 
everything builds ok and only binary packages use libtinfo. I posted the patch 
on the tinfo tracker but no one seems interested.

It's worth a shot, but it doesn't work for all packages. I think it depends on 
the linking order.

PS: There's a post by wraeth on this thread, is anybody having problems 
opening it? kmail crashes everytime I try.
