ListUtil.c: loadable library and perl binaries are mismatched (got handshake key 0xde00080, needed 0xce00080)

2018-12-07: I had this error on my Arch Linux distribution. It was probably caused because I installed Perl modules with cpan rather than using pacman.

As per this stackoverflow answer, I was able to at least temporarly get rid of this error by unsetting PERL5LIB (which pointed at /home/rene/perl5/lib/perl5) and unsetting PERL_LOCAL_LIB_ROOT which pointed at ~/perl5.
