Thanks to all of you who have tried to help me. As it turned out, comparing MD5 sum is intractable, /usr/lib64 alone contained more than 500,000 files !
The /etc tree didn't show significant differences. So, I resorted to keep my 4 cores busy over the weekend to re-emerge the whole machine. That's the price for a highly configurable and up-to-date system like Gentoo - but I like it. But it's the first time I needed to do it since several years, now. Helmut.
