I've recently upgraded to OS X Lion and Xcode 4.2, which however seems to cause a lot of problems with Ruby.
What I need to do is install 4.1 instead of the currently 4.2, but I can't seem to find it anywhere. App Store and the official download page already offers only 4.2.
Is there any way I can get back to 4.1?
you can find old versions of xcode here. Make sure to install it in a different directory.
