[ ] motion doctor does "additional things" when run in a ruby motion project directory
- [ ] "run from a RM project directory" means that the Rakefile contains a require statment to RubyMotion
- [ ] If that's the case, when motion doctor is run. It first tries to build the project.
- [ ] If the build fails containing the below error message, then doctor should run diagnostics around xcode select (version 2349 should be paired with XCode version 9.2 and RM version 5.6) :
```
xcrun: error: active developer path ("/Users/mac/Desktop/Xcode.app/Contents/Developer") does not exist
Use sudo xcode-select --switch path/to/Xcode.app to specify the Xcode that you wish to use for command line developer tools, or use xcode-select --install to install the standalone command line developer tools.
```

More ideas:

valid Android SDK/NDK path and installation
Installed SDKs compatible with current version of RM
platform tools valid and usable
emulators installed and available

C Functions and Graphics Context

Most Ruby devs do not consider the () after a function necessary. However for certain bridges to the underlying frameworks it is necessary to include the parentheses. It would be helpful to pick this error:

drawRect:': uninitialized constant Xxxxx::UIGraphicsGetCurrentContext (NameError)

When the () is missing from a call to UIGraphicsGetCurrentContext
