[gentoo-user] emerge stopped working

[Davide Carnovale]

Hi all!
i was going through a world update today and during --depclean emerge throw
an error complaining about possible corrupted binaries or hw failure.
since then it has stopped working, no matter what i try to emerge, the
command simply return to the shell without any kind of error or any other
output at all.
i fired and usb stick with the gentoo 11 live dvd and i copied over both
bash and emerge binaries to my machine, in case they were corrupted (bash
was given as the most likely) but nothing changed.
now i simply have no clue on what's wrong and how can i fix it, apart from a
full reinstall, which i'd like to avoid.

can anyone point me somewhere to solve this problem?
