I just tried to use the .dmg version of Rakudo Star.
I might not be the typical Mac user as I spent quite some time trying to figure
out what do I need to do in order to start using it after the installation.
In the end I found that it was installed to /Applications/Rakudo
Then I added these to my .bash_profile:
reloaded it and then I could use it.
Maybe some notes like this could be added to
