If you're using a Debian-derived distribution, you can use the deborphan command (which comes in the package 'deborphan') to determine what libraries are installed but not depended upon by other packages. Also, if you use aptitude you can browse through the "Obsolete and Locally Created Packages" section to find out what is no longer a needed package or library. Of course this doesn't help if you compiled anything yourself against certain libraries or if you're using another distro. tim _______________________________________________ PLUG mailing list [email protected] http://lists.pdxlinux.org/mailman/listinfo/plug
