Most ports will build fine. Some will not. GUI software is a good candidate
for failure.

The GSoC task would be to provide a method to declare this implicit dependency
in Portfiles so that we could stop showing this warning for every installation,
recommend to only install the command line tools and bail out if a port
requires Xcode but it is not installed.

This could probably be done together with rule adaptions for trace mode to hide
Xcode if a dependency was not declared, so port maintainers had a simple way to
test whether their port uses Xcode.
