Using spaces in prefix path should work now. There was some serious revamp of the build system during the last couple of months. I didn't have all the details, but some relevant pull requests for Rakudo have probably been: * https://github.com/rakudo/rakudo/pull/2693 * https://github.com/rakudo/rakudo/pull/3031
Also: $ cd ~/perl6/tmp/dir\ with\ space/ $ mkdir perl6 $ git clone https://github.com/rakudo/rakudo.git $ cd rakudo $ perl Configure.pl --backends=moar --gen-nqp --gen-moar --prefix ~/perl6/tmp/dir\ with\ space/perl6 && make install $ ~/perl6/tmp/dir\ with\ space/perl6/bin/perl6 -e 'say 42' 42 I'm closing this ticket as 'resolved'.
