Illegal instruction error on Mac (M1)

Running the following test on the M1 Mac (Desktop) leads to an Illegal instruction 4 error.

#!/usr/bin/env python3 
from aliby.pipeline import PipelineParameters, Pipeline 

params = PipelineParameters.default(general={"expt_id": 560, 
                                             "distributed": 0, 
                                             "server_info": { "host": "staffa.bio.ed.ac.uk",
                                                              "username": **REMOVED**, 
                                                              "password": **REMOVED**,}, 
                                             }) 
p = Pipeline(params) 
p.run()

@fwaharte1 is going to test it on an Intel MacBook to check whether this is M1-specific.
