I recently installed the latest version of XCode. See the signature for the latest version installed. My default GCC compiler is still 4.0, and I want to change it to 4.2. I realize I have to use sudo /usr/bin/gcc_select 4.2 in order to switch the symbolic link but I get an error stating that the command is not found. I did a search for the command file (GCC_select) in spotlight and ended up empty. Does this mean that GCC_select is no longer an option? If this is the case, how can I change my default to 4.2? Please help as I can't find any solutions on the net.
