I'd guess this is a problem with the locale. In my case an unknown
locale adds 8, rather than 10, additional lines, but still:
$ LANG=C ./foo.pl
Global symbol "$foo" requires explicit package name at ./foo.pl line 3.
Execution of ./foo.pl aborted due to compilation errors.
$ LANG=sq ./foo.pl
perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
LANGUAGE = "en_GB:",
LC_ALL = (unset),
LC_COLLATE = "C",
LANG = "sq"
are supported and installed on your system.
perl: warning: Falling back to the standard locale ("C").
Global symbol "$foo" requires explicit package name at ./foo.pl line 3.
Execution of ./foo.pl aborted due to compilation errors.
