Probable version skew in pre-compiled xxx

Question

I'm installing a package onto a virtual machine(ubuntu18.04). Here are the instructions I used:

apt-get install perl6 && \
 git clone https://github.com/ugexe/zef.git && cd zef && perl6 -I. bin/zef install . && \
 /usr/lib/perl6/site/bin/zef install Shell::Command && \
 PYTHON_CONFIG=/usr/bin/python3-config \
 /usr/lib/perl6/site/bin/zef -v install https://github.com/eatingtomatoes/Inline-Python3.git --/test --debug

Following is the output:

....

===> Installing: LibraryMake:ver<1.0.0>:auth<github:retupmoca>
===> Install [OK] for LibraryMake:ver<1.0.0>:auth<github:retupmoca>

When I executed perl6 -e "use Inline::Python3; say 'hi'" in shell, it reported:

===SORRY!===
Probable version skew in pre-compiled

The Inline::Python3 package is a perl6 package developped by myself. It runs well on my pc.

perl6 --version said:

This is Rakudo version 2018.03 built on MoarVM version 2018.03
implementing Perl 6.c.

I don't know what the 'version skew' is. How can I fix the error?

Following @jjmerelo's advice, using the latest compiler provided by rakudo-pkg solved the problem.
