I'm even further behind than Andreas, but I'm curious about the situation here. It's been a while, but last time I checked, compiling the x86 decoder with gcc took about 1GB of RAM (definitely <1.5GB). If something has happened to the code and/or gcc that really makes it take much more than that, I'm very interested in knowing.
In my experience, running in limited-memory situations because I'm compiling in a VM on my laptop, something like 2-3GB of physical memory is plenty if you're running scons with "-j 2" (or not using -j at all). If you're running into problems with 4GB of RAM, make sure you're not using a -j argument larger than 2, and that you don't have any other large memory-consuming processes running.
