patch applied (cabal): Put a header in the dist/setup-config file and check it on loading

Mon Mar 3 12:28:55 PST 2008 Duncan Coutts * Put a header in the dist/setup-config file and check it on loading This should fix ticket #120 in future which is the problem where you do something like "sudo runghc Setup install" and you accidentally end up using a different version of the compiler or of the Cabal lib and you get an unhelpful error message:

Setup.hs: error reading ./.setup-config; run "setup configure" command? Well now you'll get a helpful error message: setup: You need to re-run the 'configure' command. The version of Cabal being used has changed (was Cabal-1.3.6, now Cabal-1.3.7). If the compiler version being used has changed too we get the extra helpful: setup: You need to re-run the 'configure' command. The version of Cabal being used has changed (was Cabal-1.3.6, now Cabal-1.3.7). Additionally the compiler is different (was ghc-6.8, now ghc-6.9) which is probably the cause of the problem. Of course this does not help for older versions of Cabal but there's not a lot we can do about that.
