Comment (by kencu):

 the python c interface library was failing to build on < 10.6 on newer
 pythons, 38, 39, and we fixed that last year with this:

 [7da358db764df2913c58385f3857e248191cc460/macports-ports]

 at the time, python37 was working and didn't have that issue.  However,
 there have been several updates to python37 since then, so perhaps some of
 python38+ has been backported into python37 and might need a similar
 patch.

 That might be a place to start peeking.
