Hello, In a moment when I would have done better sleeping, I went to a plain RH9 box, downloaded the libao, libogg and libvorbis tarballs from the vorbis web site, and installed them from source: configure, make, make install. Only after that I remembered to do rpm -qa, and found that those libraries, or better their RPM coming with RH9 had been installed initially. How do I go back to a clean system (no extra/orphan/conflicting files, consistent RPM db) now? Should I do make uninstall for all the source packages, rpm -e for the rpm packagesù then install only from RPM or source, depending from the version needed?
