Typing: rpm -Uvh netscape-common-4.7-1.1.i386.rpm on a new installation from CD gives: error: failed dependencies: netscape-common = 1:4.61 is needed by netscape-communicator-4.61-12us netscape-common = 1:4.61 is needed by netscape-navigator-4.61-12 and the package is not updated.
You need to upgrade netscape-common and netscape-navigator at the same time (i.e., the same command line.)
