It allows one a bit of flexibility when upgrading large software
collections like X11 or kerberos. In my case both packages are so
fundamental to the operation of my systems that life would be
extremely painful if an upgrade to either package would fail.
One way to slowly upgrade is to recompile say X11R6.3 and install it
in a slightly different place -- say /usr/X11R6.3 instead of
/usr/X11R6.1 . Both X11 trees would of course have their own
.../lib/libX*.so.1 files. Using a global search path (such as using
"ldconfig directory-name") would force everything in the system to use
one library directory or the other. Using compiled in paths lets one
test out a new package one program at a time. Each new program uses
the new library and each old program still uses the old libraries.
