debian настройка репозитария для установки fcc for arm - v2

Мне нужно компилить в debian под arm. Для этого я прописал в /etc/apt/sources.list :

#
# deb cdrom:[Debian GNU/Linux testing _Lenny_ - Official Snapshot i386 DVD Binary-1 20081114-02:30]/ lenny contrib main

#deb cdrom:[Debian GNU/Linux testing _Lenny_ - Official Snapshot i386 DVD Binary-1 20081114-02:30]/ lenny contrib main

deb ftp://ftp.debian.org/debian/ lenny main
deb-src ftp://ftp.debian.org/debian/ lenny main

deb ftp://ftp.debian.org/debian/ lenny contrib
deb-src ftp://ftp.debian.org/debian/ lenny contrib

#deb http://www.emdebian.org/debian/ unstable main
#deb-src http://www.emdebian.org/debian/ unstable main

#deb http://buildd.emdebian.org/debian/ unstable main
#deb-src http://buildd.emdebian.org/debian/ unstable main
#deb http://buildd.emdebian.org/debian/ testing main
#deb-src http://buildd.emdebian.org/debian/ testing main

deb http://buildd.emdebian.org/emdebian/ unstable main
deb-src http://buildd.emdebian.org/emdebian/ unstable main

Правильно ли я настроил apt или надо както по другому?
