[gentoo-hardened] Revdep-rebuild doesn't finish

[Shinkan]

Hi everyone,

I know this might not be the better place to ask for that but as I use
Gentoo Hardened...
I tried to "revdep-rebuild" (after emerge -uDNa world && emerge --depclean),
but it locks at 74% with no information.
When I say "it locks", I mean it stay at 74% for more than 12 hours (then I
stopped it).
I also tried "revdep-rebuild -i -o" but the result is the same.

I there any way I can make it finish ?
More generally, are there ways to clean up my system ?
