I got Python 3000 (aka 3.0) to compile on my N810. Tip: by default, it uses -O3, which causes gcc (3.4.4) to crash. (I've seen this before; -O3 is so aggressive that some complex C code can make it choke.) Just edit the generated Makefile. It's in just one place, so just search for -O3. (The configure script seems to have no options to set the -O level; setting CFLAGS didn't work.)
