To automatically build the version of Parrot that came with this
distribution ($reqpar), try re-running Configure.pl with the
'--gen-parrot' option. Or, use the '--parrot-config' option to
explicitly specify the location of parrot_config to be used to
build Rakudo Star.

You can now use '$make' to build Rakudo Perl.
After that, you can use '$make rakudo-test' to run some local tests,
or '$make install' to create a 'perl6' executable in the local directory
and in $config{'bindir'}/perl6 .
