Unfortunately, for things that don't "just work", the changes needed tend to be very port-specific; and there's far more ports that just disable universal builds than tweak it to work, in at least some cases because untangling the changes needed for universal builds turned out to be too difficult / not worth the effort.

The link error occurs here:

It seems like its not finding the object files, which are part of the build in ../ast.
