After an installation I notice that there is some broken lib left behind: sabayon joost # ls -l /usr/lib64/librpm.so.3 lrwxrwxrwx 1 root root 15 Oct 7 19:07 /usr/lib64/librpm.so.3 -> librpm.so.3.3.1
To resolve this I have to install rpm from Entropy and remove it again. Anybody has a clue where this orphan is from?
