Rakudo: Revision 5
The "Rakudo Perl 6 Compiler"<http://rakudo.org/> ("rakudo" for short) targets the "Parrot Virtual Machine"<http://parrotcode.org/>, and it currently lives in the "languages/perl6/"<http://svn.perl.org/parrot/trunk/languages/perl6/> directory of the "Parrot repository"<http://svn.perl.org/parrot/trunk/>.
To build the Rakudo Perl 6 compiler, first "get a working copy of Parrot"<http://www.parrotcode.org/source.html>, then change to the languages/perl6/ subdirectory and type "make perl6". This will build an executable.
To run a program with Rakudo Perl 6, issue a command like
> `$ perl6 hello.pl`
Or, to run an interactive perl6, type
> `$ perl6`
For additional build instructions, you might also have a look at "this PerlMonks post"<http://www.perlmonks.net/?node_id=659584>.
parrot changes rapidly, and rakudo as well; if you have issues with the latest point release, be sure to try svn-latest of parrot/rakudo.
