py38-astropy @5.0 fails import

[odysseus9672 (Sean Lake)]

This is very similar to ticket #64029, but the error text is different. The recent update to astropy 5.0 for py38-astropy doesn't work. It's missing a dependency, perhaps? When I try to use it I get an error.

This is on MacPorts 2.7.1 with XCode 11.5 on Mac OS X 10.15.7.

Here's the output:

Traceback (most recent call last):

Yep, missing dependency in this one. Installing py38-packaging fixes this specific error, but leads to the following error:

Traceback (most recent call last):
  File "./Analysis_Pix_v7.py", line 96, in <module>
    import astropy.io.ascii as aptxt

    import yaml

And installing py38-yaml fixed this new error, and it runs now.

we experience the same with python39 and py39-astropy. Installing py39-yaml and p39-packaging solves it:
