1) I did an Ubuntu purge followed by an install. Afterwards I rebuilt ghc 6.8.2. The same d*mn  "unknown package: unix-2.3.0.0" message when I try to build

unix

 and

bytestring   via runhaskell Setup.hs configure.

2) This strongly looks like the package database manager, i.e. ghc-pkg. Source please so I can understand where this d*amn "unknown package: unix-2.3.0.0" message is coming from and why?

3) Serious rant mode on ... I am a computer industry veteran(decades) who is trying to convince, coggle, etc. younger colleagues about the usefulness of FPLs for correctness, etc, and then => "unknown package ....".

no  it doesn't.

I suspect the Cabal stuff has a dependency on the unix package (at least on POSIXish systems, probably via the filepath stuff) and by deregistering unix-2.3.0.0 which Cabal was built against you broke it.  Probably you need to do a full reinstall of GHC to recover at this point.
