Installing /Users/fc/perl5/perlbrew/build/perl-5.22.0 into ~/perl5/perlbrew/perls/perl-5.22.0 This could take a while. You can run the following command on another shell to track the status: tail -f ~/perl5/perlbrew/build.perl-5.22.0.log Installation process failed. To spot any issues, check /Users/fc/perl5/perlbrew/build.perl-5.22.0.log If some perl tests failed and you still want to install this distribution anyway, do: (cd /Users/fc/perl5/perlbrew/build/perl-5.22.0; make install) You might also want to try upgrading patchperl before trying again: perlbrew install-patchperl Generally, if you need to install a perl distribution known to have minor test failures, do one of these command to avoid seeing this message perlbrew --notest install 5.22.0 perlbrew --force install 5.22.0
