Xcode: Compile Error 71, can't find copystrings

error: can't exec '/Developer/Library/Xcode/Plug-ins/CoreBuildTasks.xcplugin/Contents/Resources/copystrin开发者_StackOverflow中文版gs' (No such file or directory)
Command /Developer/Library/Xcode/Plug-ins/CoreBuildTasks.xcplugin/Contents/Resources/copystrings failed with exit code 71

But when I navigate to that location, I have the file (copystrings).

Anybody have any solutions? Using Xcode 3.2.3 (Latest) Mac OS X 10.6.4

I'm also using the latest SVN of StepMania, if you want to look at the localization files. https://svn.stepmania.com/svn/trunk/stepmania/PBProject/

I had on old symlink to ruby. I originally thought this wasn't related to ruby... but as it turns out.. it is.

sudo ln -s /opt/local/bin/ruby /usr/bin/ruby

Make sure to delete the old /usr/bin/ruby first.
