Actually, this is not true. If a package linked to the so.5 version of
libffi, it will always be linked to that version. As long as it exists,
things are okay. However, the .so file itself that points to either the
.so.4 or .so.5 (depending on which flavor of libffi) will be overwritten.
Does this present a problem if some packages are linked to one version
of libffi and other packages link to another version?

For now, I don't think anything needs to be added to the book unless we
know that having packages linked to both versions (some to one version,
others to the other version) is a conflict.
