I'm running: This is Rakudo version 2017.01 built on MoarVM version 2017.01 implementing Perl 6.c. under Arch.
When I do $perl6 starfield.pl6 I get:Cannot locate native library 'libncursesw.so.5': libncursesw.so.5: cannot open shared object file: No such file or directory
That is because version 6 of the ncurses library is installed, rather than 5.
