appium: After upgrading to 1.2.2 (from 1.2.1), fail to start iOS device log capture via deviceconsole

After upgrading to 1.2.2 (from 1.2.1), fail to start iOS device log capture via deviceconsole.

After investigating the source code lib/devices/ios/ios-log.js, I find the error was caused by the absence of the executable devicesyslog.

$ cd /usr/local/lib/node_modules/appium/build/deviceconsole/
$ ls -1
Makefile
MobileDevice.framework
MobileDevice.h
deviceconsole.xcodeproj
main.c

So I compile it manually and the issue gets resolved. I think this step (compilation) should be done automatically.
