The install problem with the CD-ROM affects users on a Unix system. The disk was mastered on a Windows system, and the mastering tool wrote the install script in a DOS text format. There are also two lines in the script that need to be altered to properly modify the examples for your local site. You can find detailed instructions on how to convert the file to a Unix format so it will run, and what lines to change in the current errata for the book. If you run into any further problems, write us about it at bookquestions@oreilly.com. We can help you get it running.
