This all looks correct. Before you were saying you were still getting
'multiarray.pyd', now your error says 'multiarray.so'. So now you are
testing the right thing. Test test_basic2() in test_ctypeslib was fixed, but
I forgot to fix it in two other places. I updated both my branches on
github, please try again.
