If you look at the error message of this report for perl 5.22 you will see that it's running perl 5.20:
# Can't locate Getopt/ in @INC (you may need to install the Get +opt::Args module) (@INC contains: .... /etc/perl /usr/local/lib/x86_6 +4-linux-gnu/perl/5.20.2 /usr/local/share/perl/5.20.2 /usr/lib/x86_64- +linux-gnu/perl5/5.20 /usr/share/perl5 /usr/lib/x86_64-linux-gnu/perl/ +5.20 /usr/share/perl/5.20 /usr/local/lib/site_perl .) at /tmpfs/.cpan +-build-cpansand/2018091711/Anki-Import-0.029-9/blib/lib/Anki/Import.p +m line 6.
Similar results for other versions.

In your test you need to call $^X instead of perl:
Even if the tester is running the tests with a specific perl version, this perl might not be in their path.

Also you should replace /usr/bin/env perl with /usr/bin/perl in It will be replaced with the path to perl it was installed with.
