Most questions regarding this problem are due to missing Xcode; I have Xcode 4.2 installed.
Install attempt:
rvm install 1.9.3
Installing Ruby from source to: /Users/jamie/.rvm/rubies/ruby-1.9.3-p0, this may take a while depending on your cpu(s)...

GCC is available:

Thread model: posix

ls /usr/bin | grep gcc
gcc

llvm-gcc
llvm-gcc-4.2
Based on config.log (posted at bottom due to size) I tried symlinking gcc-4.2 to gcc and then installing:
rvm install 1.9.3
ERROR: The autodetected CC(/usr/bin/gcc-4.2) is LLVM based, it is not yet fully supported by ruby and gems, please read `rvm requirements`, and set CC=/path/to/gcc .
So I could probably just grab gcc elsewhere, but I\'m mostly concerned as to why this is happening. Shouldn\'t installing Xcode be enough?
