The EPERM (Operation not permitted) is caused by the sftp-server
returning SSH_FX_FAILURE, which is a generic error code.  I have no
idea what it means, and since the server is Mac OS, I can't really
help with tracing the problem there.

If there's a system call tracing tool similar to 'strace' you can try
to see what sort of error is causing the stat() operation to fail.
