I thought it was all the same thing as from cleaning up the package and adding the option to configure yes the version 5 support is built and installed but I was not aware that these were two separate installations, one for version 6 and then the other one for version 5 using the two commands in the book.  Perhaps saying this in the book like if you wish to install version 5 support you need to clean up the sources but this will not remove version 6 support that was just installed.  Nick Gawronski
