in reply to Re^2: Error Compile perl on AIX 7.1
in thread Error Compile perl on AIX 7.1

I believe this will help:
https://rt.cpan.org/Public/Bug/Display.html?id=128004

It's a bug in lib/ExtUtils/MM_aix.pm
If you make the alteration to lib/ExtUtils/MM_aix.pm as specified there, you should be successful.
Another option would be to build perl-5.30.0 or later.

Cheers,
Rob
