Fails to build on mac, workaround

[JelleZijlstra]

I can reproduce this. Interestingly, it fails while building qcore, but just running pip install qcore works fine.

Maybe the qcore headers should be changed to use relative imports, because it also warns:

    /private/var/folders/75/kbphyp697t5fzgzkth6s7x380000gn/T/easy_install-4_kiv1by/qcore-1.6.1/.eggs/Cython-3.0a5-py3.9.egg/Cython/Compiler/Main.py:344: FutureWarning: Cython directive 'language_level' not set, using '3str' for now (Py3). This has changed from earlier releases! File: /private/var/folders/75/kbphyp697t5fzgzkth6s7x380000gn/T/easy_install-4_kiv1by/qcore-1.6.1/qcore/microtime.pxd

And the errors are about how it's importing other pxd modules in qcore.

Also experienced this with the error

Running pip install qcore before pip install asynq works for me too.

I can generally install asynq fine on Mac, please report if this becomes an issue again.
