Thanks Dimitry 

  clang -v
    FreeBSD clang version 6.0.1 (tags/RELEASE_601/final 335540) (based on LLVM 6.0.1)
    Target: x86_64-unknown-freebsd13.0
    Thread model: posix
    InstalledDir: /usr/bin
  cd /usr/lib/clang ; ls
    7.0.1/
  dmesg
    FreeBSD 13.0-CURRENT JHS_Lapr amd64
    FreeBSD clang version 6.0.1 (tags/RELEASE_601/final 335540) (based on LLVM 6.0.1)

So my current box has a mismatch. 
My other current box is normaly older, so I turned on to copy 6.0.1 libs 
& found a newer & consistent current:

  clang -v
    FreeBSD clang version 7.0.1 (tags/RELEASE_701/final 349250) (based on LLVM 7.0.1)
    Target: x86_64-unknown-freebsd13.0
    Thread model: posix
    InstalledDir: /usr/bin

  dmesg:
    FreeBSD clang version 7.0.1 (tags/RELEASE_701/final 349250) (based on LLVM 7.0.1)
  cd /usr/bin; ls -l
    Dec 20

So I'm checking the newer current box with make all,
then will do a cross host recovery to the inconsistent older box.
Thanks Enji & Dimitry

Cheers,
Julian
