Re: [perl #130660] make t/spec/foo/bar.t modifies the current installation

My approach to solving this would be to have make test use perl-m resp. 
perl-j directly.

Adding another make target still leaves "make test" overwriting the 
perl6 file, which might be surprising if somebody has explicitly set up 
perl6 to mean (say) perl6-j.
