Use apt-get to upgrade, and the problem should go away. Clarification: apt-get upgrade won't help, because 4.4.1 is still the leading version in the ubuntu karmic (9.10) repositories, even if you include backports. The alternative is: apt-get install gcc-4.3 And then set CC="gcc-4.3" (or use update-alternatives).
