[Wien] w2web proplem

[Ibrahim, El-Said]

Hi 

I was installing wien2k 
and when I try to begin I find 

sal at sal-laptop:~$ w2web
perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
	LANGUAGE = (unset),
	LC_ALL = (unset),
	LC_NUMERIC = "en_US",
	LANG = "en_US.utf8"
    are supported and installed on your system.
perl: warning: Falling back to the standard locale ("C").
