Somehow, my server's ubuntu version fell between the cracks with having a proper Raku distribution [EDIT: "zef" was deleted from the distro, as seen HERE]. I have followed various online guides for installing Raku's package manager, zef, to no avail. It goes without saying that to use Raku, installing Raku modules is important. Here's what I've tried: 
#AS PER https://github.com/ugexe/zef

$ git clone https://github.com/ugexe/zef.git
$ cd zef
$ raku -I. bin/zef install .

[download]
Having done the above from within my /usr/src directory, this resulted in a download and supposed install of the zef application. However, attempting to run "zef" at the command line resulted in.... 
Command 'zef' not found, did you mean:
  command 'zec' from deb zec (0.12-5)
  command 'zed' from deb zfs-zed (2.1.5-1ubuntu6~22.04.1)
Try: apt install <deb name>

[download]
Not to be so easily deterred, I navigated to zef's /bin directory where the zef binary file was, and ran ./zef --help from there. This yielded the following results: 
===SORRY!=== Error while compiling /usr/lib/perl6/zef/bin/./zef
Could not find Zef::CLI in:
    inst#/root/.raku
    inst#/usr/lib/perl6/site
    inst#/usr/lib/perl6/vendor
    inst#/usr/lib/perl6/core
    ap#
    nqp#
    perl5#
at /usr/lib/perl6/zef/bin/./zef:3

[download]
Noticing that the /usr/lib/perl6 directory seemed to be in the expected path, I moved the entire zef directory there, only to arrive at the same results.

An internet search then yielded another hope, which I tried--a page which claims to have been updated this very day. 

#AS PER https://linux-packages.com/ubuntu-jammy-jellyfish/package/perl
+6-zef

perl6-zef on Ubuntu 22.04 LTS (Jammy Jellyfish)

Last updated: December 28,2023
1. Install perl6-zef package

Please follow the step by step instructions below to install perl6-zef
+ package:

  sudo apt update
  sudo apt install perl6-zef

[download]
Having completed the above steps, the results of the latter one were as follows: 
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
E: Unable to locate package perl6-zef

[download]
...and I am essentially right back to where I began, with no 'zef' at all. An apt-cache search perl6 shows no zef option. It has only the following: 
dh-perl6 - debhelper add-on to simplify Perl 6 package building
libexport-attrs-perl - Perl 6 'is export(...)' trait as a Perl 5 attri
+bute
libmethod-signatures-perl - method and function declarations with sign
+atures and no source filter
libparse-method-signatures-perl - Perl module to parse Perl6-like meth
+od signatures
libperl6-caller-perl - Perl6-like OO caller() interface for Perl 5
libperl6-export-attrs-perl - Perl 6 'is export(...)' trait as a Perl 5
+ attribute
libperl6-export-perl - implementation of the Perl 6 'is export(...)' t
+rait
libperl6-form-perl - Perl 5 implementation of the Perl 6 'form' built-
+in
libperl6-junction-perl - module providing Perl6-style Junction operato
+rs in Perl5
libperl6-say-perl - module to print without newline needed
libperl6-slurp-perl - module implementing the Perl 6 'slurp' built-in
libsyntax-keyword-junction-perl - Perl6 style Junction operators in Pe
+rl5
nqp - Not Quite Perl compiler
nqp-data - Data files for NQP compiler
perl6-readline - Readline binding for Perl 6
raku-getopt-long - Getopt implementation for Raku
rakudo - Perl 6 implementation on top of Moar virtual machine

[download]
Searching apt for 'zef' strangely nets this: 
picard-tools - Command line tools to manipulate SAM and BAM files

[download]

Advice for correct installation of Raku's package manager on the latest Ubuntu LTS would be greatly appreciated.

Blessings,
