OpenWRT su 504T problema X-WRT

[borexino]

Ciao a tutti!
Dopo tanto pensare sono riuscito ad installare OpenWRT sul mio vecchio 504T. Il problema ora è l'interfaccia web X-WRT!
sto cercando di installarla con opkg:

opkg install ftp://ftp.berlios.de/pub/xwrt/webif_latest_stable.ipk

ad un certo punto ecco cosa mi esce:

Collected errors:
 * Package base-files-uci wants to install file /lib/config/uci.sh
	But that file is already provided by package  * uci

Si può risolvere in qualche modo?

Grazie
