Permissions problems with py38-xarray @0.16.0

[quintusdias (John G Evans)]

There seems to be a permissions problem with this port, many of the installed *.py files have permissions 600 and therefore are not readable by an unprivileged user. Running the test suite as an unprivileged user results in failures. Uninstalling and reinstalling the port does not change anything, but manually adding read permission on the *.py files is a band-aid that seems to get things working again.

I'm also getting something very similar for python 3.7 and 3.8 versions:
