Let's say something like this is being returned.
Dumper.c: loadable library and perl binaries are mismatched (got handshake key 0xdb00080, needed 0xdb80080)
Notice in this example that the error starts with Dumper which means there is some issue with the Data::Dumper module in this example.
I first happened upon this after I installed the Data::Dumper module into a specific version of Perl.
cpanm install --local-lib /usr/local/share/perl5/5.32 Data::Dumper
The error probably means that the module in question (Data::Dumper in this example) is already installed thus Perl doesn't know which module to use. If possible, the quick and easy fix would be to remove the installation of the module that you installed.
cpanm --uninstall --local-lib /usr/local/share/perl5/5.32 Data::Dumper
