Ugh. The new u-a is stricter and errors out. If you edit the file 
/opt/sw/fink/dists/stable/main/finkinfo/libs/pythonmods/dill-py.info so 
that in both PostInstScript() and PreRmScript(), the
`update-alternatives --auto dill` command (lines 40 and 51) is inside 
the `if [ -f %p/bin/dill-py ]; then` conditional, does that work? Run 
`fink rebuild dill-py38; fink reinstall dill-py38`

The conditional should now look like this (all else in those scripts 
stay the same:

if [ -f %p/bin/dill-py ]; then
	update-alternatives --auto dill
	update-alternatives --verbose --remove dill %p/bin/dill-py%type_raw[python]
fi
