Unable to install on OSX 10.9 (Mavericks) with XCode Command Line Tools installed

What steps will reproduce the problem?
1. Install Xcode Command Line Tools
2. Install node-gyp under OSX 10.9 (Mavericks)

What is the expected output? What do you see instead?

Expected - Gyp and node-gyp would install successfully.

However, instead we get:

    > hiredis@0.1.15 install /Users/victorhooi/code/collaborative-markdown/node_modules/derby/node_modules/racer/node_modules/share/node_modules/livedb/node_modules/hiredis
    > node-gyp rebuild

    xcode-select: error: tool 'xcodebuild' requires Xcode, but active developer directory '/Library/Developer/CommandLineTools' is a command line tools instance

What version of the product are you using? On what operating system?

Please provide any additional information below.

We've raised an issue with the node-gyp:

However, the maintainer there said that this was an upstream issue with gyp,
