You might want to run `apt-get -f install' to correct these:
The following packages have unmet dependencies:
  build-essential: Depends: libc6-dev but it is not going to be installed or
                            libc-dev
                   Depends: libc6-dev-sparc64 but it is not going to be installed
                   Depends: gcc (>= 3:3.3) but it is not going to be installed
                   Depends: g++ (>= 3:3.3) but it is not going to be installed
                   Depends: dpkg-dev (>= 1.4.1.19) but it is not going to be installed
  smbclient: Depends: samba-common (= 3.0.37.netgear2) but 2:3.5.15-netgear1 is to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

My sources.list is quite simple:

# cat /etc/apt/sources.list 
deb http://www.readynas.com/packages readynas/

deb http://archive.debian.org/debian sarge main contrib non-free

deb-src http://archive.debian.org/debian sarge main contrib non-free

What bugs me is the samba-common dependency that keep appearing, shouldn't have anything to do with the particular installation. It appears every time I run apt-get.
