If you don't do this, then when you update e.g. only some of the gnome libraries without recompiling all of gnome, then your gnome binaries will have libraries linked to libc.so.6 and libc.so.7, and to libkse.so.2 as well as libthr.so.3, and this is a guaranteed runtime crash because these are mutually inconsistent sets of libraries. The mailing list archives have many examples of people who ran into this in the past. Kris
