I was a happy user of perl on my old MBP under El Capitan. I moved to new MBP which had Sierra on it Everything broken. I installed Perlbrew and the latest Perl. Cpan, cpanm, Spreadsheet::XLSX - went to run my old program - and it crashes with "Parser for XLSX is not installed at live.pl line 50." I tried also installing Spreadsheet::XLSX" - to no effect. Did something change in the last couple of months or is this some Sierra problem? I'm out of things to try.
