Comment 17 for bug 1531833

I guess here 's the problem:
perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
 LANGUAGE = (unset),
 LC_ALL = (unset),
 LC_TIME = "hu_HU.UTF-8",
 LC_MONETARY = "hu_HU.UTF-8",
 LC_ADDRESS = "hu_HU.UTF-8",
 LC_TELEPHONE = "hu_HU.UTF-8",
 LC_NAME = "hu_HU.UTF-8",
 LC_MEASUREMENT = "hu_HU.UTF-8",
 LC_IDENTIFICATION = "hu_HU.UTF-8",
 LC_NUMERIC = "hu_HU.UTF-8",
 LC_PAPER = "hu_HU.UTF-8",
 LANG = "en_US.UTF-8"
    are supported and installed on your system.
perl: warning: Falling back to the standard locale ("C").
locale: Cannot set LC_ALL to default locale: No such file or directory
