[CrAzYjOn]

Im getting a strange problem running the ./tools/wineinstall

it does the configure and part of the make fine, but then starts looping 
over and over with teh following..

perl: warning: Please check that your locale settings:
        LANGUAGE = "en_US:en",
        LC_ALL = (unset),
        LC_CTYPE = "en_US",
        LC_COLLATE = "en_US",
        LC_TIME = "en_US",
        LC_MESSAGES = "en_US",
        LC_MONETARY = "en_US",
        LC_NUMERIC = "en_US",
        LANG = "en"
    are supported and installed on your system.
perl: warning: Falling back to the standard locale ("C").

-mpreferred-stack-boundary=2 -fPIC -D__WINE__ -D_REENTRANT
-I/usr/X11R6/include -o ncurses.o ncurses.c
