CI system cryptic error

Hi there,

Recently, I created a test package for python-imaging, and the CI system 
gave a build error that I didn't see locally:

*** ERROR: unknown wheel filename.

This only occurred for the Python 3.8 build (3.6 and 3.7 are 
unaffected). Considering some of the library name changes between these 
versions, is it possible that this is a bug in the CI tool setup or in 
cygport?

Attached is the offending cygport file that caused the error.
