Command Not Found error in pre-requisite steps

[delara38]

Hello,

I am following the pre-requisite steps and when I cd into /sempre/ and type ./pull-dependencies core I get the following error:

===== Downloading core: Core utilities (need to compile)

Can't find anything on the sempre repository related to this problem. Have tried to setup on both a MacOS 15.0.1 and Ubuntu 20.04 and get the exact same error. Thank you in advance for your help!
