gtk3 @3.24.34_2 (NetSurf dependency) build fail on Mojave

[chillin-]

Unsuccessful NetSurf build due to (at least) gtk3 build fail.

macOS 10.14.6 w/ Xcode 11.3.1 on Macmini6,2

(NetSurf build on OS X 10.8.5 w/ Xcode 5.1.1 on Macmini5,2 appears successful, I just don't know how to use gtk applications and can't get NetSurf to launch, "can't open display.")
