% moar  --execname="/usr/bin/perl6" --libpath="/usr/share/nqp/lib" --libpath="/usr/lib/nqp/lib" --libpath="/usr/share/perl6/lib" --libpath="/usr/share/perl6/runtime" --libpath="/usr/lib/perl6/runtime" --libpath="/usr/lib/perl6/runtime/dynext" --libpath="/home/gregoa/.perl6/2015.09/lib" /usr/share/perl6/runtime/perl6.moarvm
