I'm presently doing a fresh install of Crux-3.0. Everything works fine, 
except the gcc update to 4.7.3. Output ends with these lines:

If you meant to cross compile, use `--host'.
See `config.log' for more details.

make: *** [bootstrap] Error 2

Any ideas? It sounds somewhat weird that gcc "can't run C compiled
