Same thing: Can't locate Digest/MD5/File.pm in @INC (@INC contains: /root/perl5/lib/perl5 ...

I guess you have a Perl version lower than 5.18:

When require encounters an unreadable file, it now dies. It used to ignore the file and continue searching the directories in @INC [perl #113422]. 
  # Perl 5.10
$ perl -I/root -MTesting
Can't locate Testing.pm in @INC (@INC contains: /root ...

  # Perl 5.24
$ perl -I/root -MTesting
Can't locate Testing.pm:   /root/Testing.pm: Permission denied.
