That is a good find. Perhaps we could check for that in sanity.bbclass?
Is it commonly available in distributions like centos?
I am afraid the perl module (Text::Template) is not common,
available on most distro, since they do not need to build
openssl :(
But I am curious that without that perl module, the build seem
ok with newer perl (perl v5.22.1 in ubuntu 1804 and without
Text::Template)
I am going on digging the root cause why the build works well
without the perl module
I know the reason
It will try to use Text::Template, if failed it fallback to load the old
one in perl source
[snip util/dofile.pl]
use with_fallback "Text::Template 1.46";
[snip util/dofile.pl]
[snip util/perl/with_fallback.pm]
sub import {
shift;
use File::Basename;
use File::Spec::Functions;
foreach (@_) {
eval "use $_";
if ($@) {
unshift @INC, catdir(dirname(__FILE__),
"..", "..", "external", "perl");
my $transfer = "transfer::$_";
eval "use $transfer";
shift @INC;
warn $@ if $@;
}
}
}

Bundle the non core Perl module Text::Template
Because we're using Text::Template and we know it's a non core Perl
module, we choose to bundle it into our source, for convenience.
external/perl/Downloaded.txt document what modules we choose to bundle
this way and exactly where we downloaded it from.
With this changes comes the transfer module for with_fallback.
