Have you tried asking Python-dev for help with this? Hopefully they would have some weight there.
It seems both GCC dev and Apple (for GCD and Accelerate) has taken a similar stance on this. There is tiny set of functions the POSIX standard demands should work on both sides of a fork without exec, but OpenMP, GCD, BLAS or LAPAPCK are not included. As long as there is no bug, it is hard to convince them to follow Intel and allow fork-based multiprocessing.
As it stands now, using Intel compilers and MKL is the only way to make this work, but Intel's development tools are not freeware.
