Upgrade Sub::Name to 0.09 and try installing Devel::NYTProf normally as the issue described in https://github.com/timbunce/devel-nytprof/issues/34 seems to have been fixed
Install Sub::Name manually before Devel::NYTProf because (probably) Perl already has an older version of Sub::Name and cpanminus doesn't bother to upgrade it
