Well, this isn't the _best_ way:

> $ mv /home/nxuser/pp/lib/libstack.so /home/nxuser/pp/lib/libstack.so.old
> $ cp libstack.so /home/nxuser/pp/lib/libstack.so
> $ rm /home/nxuser/pp/lib/libstack.so.old

The problem is that there is a time when there is no DSO available with
that name.  Just use

$ cp libstack.so /home/nxuser/pp/lib/libstack.so.new
$ mv /home/nxuser/pp/lib/libstack.so.new home/nxuser/pp/lib/libstack.so

This will atomically replace the names.
