OK thanks, I used to do this by grepping /var/lib/dpkg/info/* > Are there other signs that glibc is broken on your system? Well, I don't know. I pointed apt-get to unstable in order to install something (xmps??), which ended up upgrading my libc and some other stuff (C++ libraries??). This broke something else (undefined symbols in some X libraries when compiling stuff). So I manually downgraded libc (and hopefully all the other things that had been upgraded) via ftp + dpkg. Now I have the stable libc again, but as you suggest, I may have broken something in the process. I've now got ldd from the ldso deb. -chris
