Yes, indeed that could be relevant. I have:

macOS 10.13.6 17G10021
Xcode 10.1 10B61 

but I added the 10.13 SDK to support universal building:

$ ls -la /Library/Developer/CommandLineTools/SDKs
total 0
drwxr-xr-x  5 root      wheel  160 23 Nov 17:24 .
drwxr-xr-x  5 root      admin  160  6 Oct  2017 ..
drwxr-xr-x  7 root      wheel  224  3 Nov  2018 MacOSX.sdk
drwxr-xr-x  5 cunningh  admin  160  9 Oct 23:54 MacOSX10.13.sdk
lrwxr-xr-x  1 root      wheel   10  3 Nov  2018 MacOSX10.14.sdk -> MacOSX.sdk


but not in Xcode, I notice, which has been updated since I added that SDK, and in so doing has removed the SDK I had added in Xcode:

$ ls -la /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs
total 0
drwxr-xr-x  4 root  wheel  128  3 Nov  2018 .
drwxr-xr-x  5 root  wheel  160 19 Oct  2018 ..
drwxr-xr-x  7 root  wheel  224 18 Oct  2018 MacOSX.sdk
lrwxr-xr-x  1 root  wheel   10  3 Nov  2018 MacOSX10.14.sdk -> MacOSX.sdk


so there is an inconsistency there that might well trigger such a situation and odd error due to some baked-in path that manifests oddly.

I have uninstalled all ports, and am starting the +universal build from scratch, and so far, everything is building +universal without a hiccup using that MacOS10.13.sdk.
