Building devel/llvm60 on FreeBSD 12.0

[Carmel NY]

Has anyone, besides me of course, had a problem building "devel/llvm60" after
updating to FreeBSD 12.0-RELEASE?

My build, using poudriere, keeps ending with this error message:

c++: error: unable to execute command: Killed
c++: error: clang frontend command failed due to signal (use -v to see
invocation)
FreeBSD clang version 6.0.1 (tags/RELEASE_601/final 335540) (based on LLVM
6.0.1)
Target: x86_64-unknown-freebsd12.0

My system:
uname -a
FreeBSD scorpio.seibercom.net 12.0-RELEASE FreeBSD 12.0-RELEASE r341666 GENERIC  amd64


Thanks!
