This is ugly and shouldn't need to see the light of day. I consider this package evidence enough that perl6 won't be released a minute too soon.
To install Data::Dimensions, copy and paste the appropriate command in to your terminal.
cpanm
cpanm Data::Dimensions
CPAN shell
perl -MCPAN -e shell install Data::Dimensions
