Failure to install Inline-Perl5

See this issue: niner/Inline-Perl5#191

This is surely caused by some Perl Packer side effect.

The issue also shows when using Rakubrew in env mode. In that mode Rakubrew is in no way involved in running executables or scripts (such as zef). So I'm now sceptical this is a Rakubrew issue after all.
