So the fixes have not been released.

This also fails.  What file is it trying to access?  A clearer error
message would be helpful.

For the test suite, it needs to do some checks first before trying to
run all these tests.  I definitely don't think this should be called
by check-local at present.  It requires too much manual setup and
won't work on most platforms.
