Can't precompile when using some external module - raku

Question

I'm trying to precompile external files to get their assets with this script:
#!/usr/bin/env perl6
use v6;
use nqp;
my $precomp-store = CompUnit::PrecompilationStore::File.new(prefix => "/tmp".IO);
our $precomp = CompUnit::PrecompilationRepository::Default.new(store => $precomp-store);
my $file = "./test.pm6";
my $io = $file.IO;
my $id = nqp::sha1(~$file);
my $handle = $precomp.load($id)[0];
without $handle {
$precomp.precompile($io, $id, :force);
$handle = $precomp.load($id)[0] // fail("Could not precompile $file for $!");
}
The file I'm using is this:
use Test;
=begin pod
This is a simple pod
=end pod
If I turn RAKUDO_MODULE_DEBUG on, it fails with more stuff, but the important part is here:

The gist of it is that it's not finding the module Test. This probably means that PrecompilationRepository is trying to find Test in the context of the same precompilation repository, which makes sense. So the question is: is that assumption correct? If it is, how can we inject that library path into the precompilation store? Or should we just use the default precompilation store? How could we do that?
