Hi, 

I've written a script to build the squeak vm from scratch on Linux in one command. It's here http://github.com/lolgzs/easy_squeakvm 
To build the VM, just get the the script and
./easy_squeakvm.sh

This will
- checkout squeakvm sources from svn repository
- download PharoCore image
- load VMMaker into PharoCore
- generate the interpreter
- build the VM
- put binaries in out/squeakvm, ready to use

I was tired of typing the same commands over and over :)

Cheers,

Laurent Laffont
