MacVim with MacPorts and Xcode 7.2 failure

If the install of MacVim with MacPorts fails with error, that says something like this in the log:

"Could not find service "com.apple.CoreSimulator.CoreSimulatorService" in domain ......"

The solution would be change permissions on the: /Applications/Xcode.app/Contents/Developer/Library/PrivateFrameworks/CoreSimulator.framework/Versions/A/XPCServices/com.apple.CoreSimulator.CoreSimulatorService.xpc

with:

sudo chmod g-w com.apple.CoreSimulator.CoreSimulatorService.xpc

Enjoy!
