Erreur dans make xconfig

[widax@free.fr (DavenRave)]

Bonjour,

je voudrai migrer de la 2.4.18 a la 2.4.22 et j obtiens l erreur
suivante lorsque j execute la commande 'make xconfig' :
------------------------------------------------------
rm -f include/asm
( cd include ; ln -sf asm-i386 asm)
make -C scripts kconfig.tk
make[1]: Entering directory `/usr/linux-2.4.22/scripts'
cat header.tk >> ./kconfig.tk
./tkparse < ../arch/i386/config.in >> kconfig.tk
echo "set defaults \"arch/i386/defconfig\"" >> kconfig.tk
echo "set ARCH \"i386\"" >> kconfig.tk
cat tail.tk >> kconfig.tk
chmod 755 kconfig.tk
make[1]: Leaving directory `/usr/linux-2.4.22/scripts'
wish -f scripts/kconfig.tk
Application initialization failed: no display name and no $DISPLAY
environment variable
Error in startup script: invalid command name "button"
    while executing
"button .ref"
    (file "scripts/kconfig.tk" line 51)
make: *** [xconfig] Error 1
------------------------------------------------------

Merci d avance pour votre aide.
