Here you can download a pre-compiled version of the Squeak 3.7-7 VM for Nokia 770 with the patch posted by Onne

I installed the X Terminal Emulator and the Dropbear SSH package on my 770 and copied the VM with scp from my mac:

• tar -xvzf squeak-3.7-7-vm.tar.gz
• scp -r usr/local root@<ip-address-of-770>:/usr

You also might install some missing libs on the Nokia 770 (please read Additional install info for Squeak on Nokia 770 by Aaron).
Run apt-get as root - connect to the 770 with ssh root@<ip-address-of-770>

• apt-get install libsm6

The image, changeset, and source files are located on the memory card (copied via USB) and I start Squeak with the shell command (Terminal):

• /usr/local/bin/squeak /media/mmc1/<squeak-image> &

Enjoy it!
