These were my steps (from the install.txt):
http://tablets-dev.nokia.com/4.1/INSTALL.txt

download http://repository.maemo.org/stable/d...install_4.1.sh

Run:
sudo chmod a+x ./maemo-scratchbox-install_4.1.sh
sudo ./maemo-scratchbox-install_4.1.sh

Note you will need to specify users - this paragraph from install is a bit vague but describes it. See the scratchbox documentation. You will need to logout (I would suggest logging out of X) and login again for it to work after doing this. You may be able to do this after installling the rootstraps

download:
http://repository.maemo.org/stable/d...install_4.1.sh
(this installs the rootstrap toolchains)

Run: (you need the -y if you've already run this)
sh maemo-sdk-install_4.1.sh -y

In the above cases, tell it to install everything including any nokia binary-only packages and all the debug stuff. "Runtime Environment + All Dev and Dbg Packages."
