Mac OS X Lion Xcode problems using RVM

Question

I had Xcode 4.1 preview 5 working fine but decided to upgrade to the final xcode 4.1 thru the App store. I uninstalled Xcode first...

sudo /Developer/Library/u         


        

Answer 1

Guy's answer above seems to fix the problem compiling Ruby in RVM with XCode 4.2 installed completely, and removed for me to install GCC from https://github.com/kennethreitz/osx-gcc-installer . This is preferable for users needing to have both RVM and XCode 4.2 installed.
