python subpackage build error ... not a supported wheel on this platform

Sat Mar 12 17:54:36 GMT 2022

Building locally I get the message below on 64 & 32 bit package builds:

ERROR: python_nghttp2-1.47.0-cp38-cp38-cygwin_3_3_4_x86_64.whl is not a 
supported wheel on this platform.

but not in the confines of a scallywag build: what do I need to remove 
or change to build locally?

Most relevant lines from cygport ... all are attached (sanitized).

Take care. Thanks, Brian Inglis, Calgary, Alberta, Canada
