Downloading and building Rakudo Perl

Best practice is to obtain from github

See http://rakudo.org/how-to-get-rakudo

$ git clone git://github.com/rakudo/rakudo.git
$ cd rakudo
$ perl Configure.pl --gen-parrot
$ make
$ make test           # run internal tests
$ make spectest       # run official test suite

• We almost have 'make install' working... see next release.
