When I run xcodebuild command on the macbookpro, I got these warning:
objc[49709]: Class AMSupportURLConnectionDelegate is implemented in both ?? (0x1f32cc188) and ?? (0x1164502b8). One of the two will be used. Which one is undefined.
objc[49709]: Class AMSupportURLSession is implemented in both ?? (0x1f32cc1d8) and ?? (0x116450308). One of the two will be used. Which one is undefined.
Command line invocation:
/Applications/Xcode.app/Contents/Developer/usr/bin/xcodebuild

Can anyone tell me what's wrong and how to fix it?

Just notice I got the same warning today. I even tried uninstalling Xcode and reinstalling Xcode. Doesn't seem to help.
