From: "J. D." Date: 2004-11-06T06:18:41+09:00 Subject: Re: Building One-Click Installer with latest snapshot source I changed another line and created the directory to fix the problem. Long story short, line 123 fo builder.rb was changed to: T:/rubyinstaller/rubyinstaller/installer-win/stable/download/ruby And it seems to work now. The clue was the attempt to 'cd win32' and run 'configure.bat'.
