Try adding -mthread to the linker command line (I'm not sure about the
spelling, for check the docs). Or add -DBOOST_DISABLE_THREADS to the
compiler options and rebuild. This assumes you're using gcc 3.3.

BTW, it's always a good idea to specify the version of compiler you're
using, for gcc it can be obtained with "gcc -v".
