You can try installing gcc/g++, make etc and compiling it yourself (or cross-compiling). Getting gcc & g++ installed is a bit of a pain, but there are some good guides on google.

You'll also need to (temporarily) increase your /tmp dir size or redirect TMPDIR for gcc - otherwise you'll run out of space.

I have a build running at the moment, it's been running for a couple of hours - fingers crossed it succeeds.

Cross-compiling is probably the way I'd go if I were to start again from scratch.
