Hi Ben,
Any update on this? I'm running into what I think is the same issue with undefined tbb references even though I am setting --disable-tbb. This is with libmesh-0.9.1pre from git this evening.

thanks,
Jim

checking /usr/include/tbb/task_scheduler_init.h usability... no
checking /usr/include/tbb/task_scheduler_init.h presence... no
checking for /usr/include/tbb/task_scheduler_init.h... no
checking whether the compiler supports std::thread... no
checking whether TBB supports tbb::tbb_thread… yes



Looks like the issue is me looking for std::thread and falling back to tbb:thread, which somehow is succeeding (intel compiler likely including it) and the test is being run even if --disable-tbb is passed.  I'll add some m4 foo to skip the tbb:thread fallback when TBB is turned off.
