[dan@alexandria nqp]$ perl Configure.pl --no-silent-build --prefix=/home/dan/Source/perl6/install/ --backends=moar && make -j12 install
Found /home/dan/Source/perl6/install/bin/moar version 2019.07.1-351-g4f4c304ba, which is new enough.
Cleaning up ...
You can now use 'make' to build NQP.
After that, 'make test' will run some tests and
'make install' will install NQP.
