After installing Xcode CLT 4.5.1 on OS X 10.8.2, I'm having issues installing native ruby gems which need to compiled.
The output error is the same as with running xcrun -find:
xcode-select: Error: No Xcode is selected. Use xcode-select -switch , or
see the xcode-select manpage (man xcode-select) for further information.
To which CLT location should xcode-select point to, since it's no longer at /Developer?
Edit: I don't have the Xcode app installed, only CLT.
The new location seems to be (be sure to run as root):
sudo xcode-select -switch /Library/Developer/
