 The build fails thusly:

 }}}


 Some digging on stackoverflow suggests that grpc ''requires''
 cython>=0.29.8,<3.0.0rc1 but macports has 3.0.10.
 I have installed py310-cython-compat @0.29.37, but I can't run it, and the
 build of grpc does not appear to be able to find it (it installs into
 /opt/local/lib/py310-cython-compat/ which seems unlike other python
 installs).
