Due to an unfortunate incompatibility with the latest coreutils that was not noticed until right before release, a working copy of "checkinstall" was not available at the time of the Slackware 12.0 release. Stuart Winter was kind enough to upgrade slacktrack (a similar tool) to work around the issue of installwatch not working, but in order to do that every file on the system has to be "touched" so that changed timestamps can be used to find files that are new. Obviously, you will not want to do that on a production system (but it is always best to have a dedicated "build box" anyway). A new and working checkinstall might also be availible by the time you read this. The project's homepage is: http://asic-linux.com.mx/~izto/checkinstall Sorry for any inconvenience.
