Running VirtualBox VM host on ReadyNAS Pro

Have gotten down to apt get update step but get the following errors

nas-EA-33-DF:/# apt-get install build-essential Reading package lists... Done Building dependency tree... Done build-essential is already the newest version. 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: make but it is not going to be installed Depends: dpkg-dev (>= 1.13.5) but it is not going to be installed g++-4.1: Depends: libstdc++6-4.1-dev (= 4.1.1-21) but it is not going to be installed E: Unmet dependencies.

When I try to proceed using the make menuconfig or make clean step I obviously get "no command error". Any help would be appreciated.
