QT5-DECLARATIVE FreeBSD compile issues

[Jason Naughton]

Hi all,

I'm attempting to compile virtualbox-ose on FreeBSD 11.4 but it fails to
compile due to a dependency on qt5-declarative.  I'm compiling 5.15.2 The
compile stops at:

Try to set MAKE_JOBS_UNSAFE=yes and rebuild before reporting the failure to

Stop.
make: stopped in /usr/ports/x11-toolkits/qt5-declarative

Any Idea how to resolve this?
