[Haskell-cafe] library version problem

Before I got your email, I deregistered unix-184.108.40.206 which made my
unix-220.127.116.11 namespace changes visible. However, deregistering seems to made
other things worse, e.g. runhaskell Setup.hs configure gives an error
message "unknown parameter package: unix-18.104.22.168". Sigh .. how do I get back
to where i was in order to do a "hide"?
Kind regards, Vasili
