Did you run `xcode-select` after you moved Xcode.app?

What's the output of `xcode-select -p` ?

Look at `man xcode-select` for the different options available. You 
might need to switch the path and use quotes around the "/Volumes/LaCie 
Thunderbolt RAID Set 1/Applications/Xcode.app" path. *Maybe* that help 
when the path is transferred to other uses (like in the compiler command).
