pycurl is built against libcurl using c-ares, as the above shows.
Please confirm that your standalone curl is not (post the output of
`curl -V`).

It must follow that c-ares does not consult the mechanism via which
your "nas-29-ee-87" is defined - hosts file? NetBIOS/winbindd?

If you do not have "nas-29-ee-87" in your hosts file try adding it
there.
