Update Tru64 4.0F -> 5.0A

[Ralf Puchner]

Spider,

sorry but this procedure have worked on many system which have reported similar problems.
It is easy, requires no skills and worked several times. It will not fix the C2 database problem itself that is right, but it is a starter to recreate the C2 environment after restoring an old database file (if v5.x system runs before) or to start from scratch after removing the C2 files (e.g. replacing the current files within /etc/auth/system with the "." template files).
