xcodebuild internal error for Xcode 4.6.3

Question

I updated Xcode to 4.6 on Lion, and I deleted /Developer directory.

Then, when I tried to execute xcodebuild, I got this error.

xcodebuild 
xcodebuild: error: developer tools not installed; download from http://developer.apple.com

I soft-linked the xcodebuild inside the Xcode app:

sudo ln -s /Applications/Xcode.app/Contents/Developer/usr/bin/xcodebuild /usr/bin/xcodebuild

However this time, I got internal error.

Abort trap: 6

What might be wrong? I have xcode 4.6.3.

xcodebuild -version
Xcode 4.6.3
Build version 4H1503

Reinstall didn't solve the issue, emptying the trash (and preferably reboot) removed this error message.
