Running `buildtool` on OSX

[Gustavo Tavares]

Hello!

So I have a version of `tools-buildtool` on my Mojave Mac.

I was able to build it. On running it though—I got this error: 

> buildtool

dyld: lazy symbol binding failed: Symbol not found: _ASSIGN

  Referenced from: /Users/gtk-air/Library/Frameworks/XCode.framework/XCode

  Expected in: flat namespace

dyld: Symbol not found: _ASSIGN

  Referenced from: /Users/gtk-air/Library/Frameworks/XCode.framework/XCode

  Expected in: flat namespace

Abort trap: 6

Not sure what to do :/

What should I try?

Running `grep -R __ASSIGN .`  shows *.o and *.dylib files so this is a bit above my pay-grade at present.

Thank you,

Gustavo
