Add Perl 6 repo with fresh packages

```
sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 379CE192D401AB61
echo "deb https://dl.bintray.com/nxadm/rakudo-pkg-debs `lsb_release -cs` main" | sudo tee -a /etc/apt/sources.list.d/rakudo-pkg.list
```

Install rakudo-pkg and nothing else

`sudo apt-get update && sudo apt-get install rakudo-pkg`

Add our local and global Perl 6 paths into $PATH

`/opt/rakudo-pkg/bin/add-perl6-to-path`

Reload current user session to read PATH update

`source /home/$username/.profile`

Clone zef at 0.7.4 tag and install it by hands

```
git clone --branch 0.7.4 https://github.com/ugexe/zef.git
cd zef
perl6 -I. bin/zef install .
```

At this stage, we have Perl 6 2019.03.1 installed by rakudo-pkg
and zef v0.7.4 installed by us manually

Now we can install some packages:

```
zef install Readline
```
