Root Installing Marketplace on Fresh Nook+Android

[eldorann]

The Marketplace won't install on my NC when following the instructions at Convert the B&N NOOK Color into a Honeycomb 3.0 Android Tablet. The breaking point is to the section "Load Android SDK".

I can proceed through the steps to make ADB work on the Nook,

>adb devices
List of devices attached
2011030095882009 device
​

Next is the final step to install Android Marketplace.
Starting at step 1 returns this error.

>adb shell mount -o rw,remount -t ext2 /dev/block/mmcblk1p2 /system
mount: not found
​

With the directory being unmounted, no other commands can be used and I can not complete installing the app store.

I am a complete newbie to Nook<>Android installation and can't understand why a simple "mount" is not found.
