| Subject: | ExtUtils::MakeMaker version requirement should be 6.57_02 |
Makefile.PL has a version requirement of ExtUtils::MakeMaker 6.46 but support for the use of an arrayref for AUTHOR as used in IO::Socket::SSL 1.91 was only introduced in ExtUtils::MakeMaker version 6.57_02. As there were AUTHOR-related bugs fixed after that point, it might be wise to require version 6.58.
Using an older version results in this:
$ perl Makefile.PL INSTALLDIRS=vendor
WARNING: AUTHOR takes a string/number not a ARRAY reference.
Please inform the author.
Checking if your kit is complete...
Looks good
only nested arrays of non-refs are supported at /usr/share/perl5/ExtUtils/MakeMaker.pm line 684
That was with ExtUtils::MakeMaker version 6.56.
The version requirement should also be specified in META.yml.
I also came across an issue with ancient versions of openssl:

That was with openssl 0.9.7f. The oldest version I have that works is 0.9.8a,
so whatever problem that caused that failure was fixed somewhere between those two versions. I suspect there aren't many people running a fairly modern Net::SSLeay and old openssl though.
