Didn't you recently fix this in nacl_io?   Perhaps we can avoid
this by depending on a very recent version of the SDK.

[Matthew Turk, 2014/01/22 21:14:31]

Good catch.  I've removed the chunk of the patch, but don't know how to mandate
the SDK except by assumption.

[Sam Clegg, 2014/01/22 22:22:26]

I think you can do MIN_SDK_VERSION=34 in pkg_info

++try:
++    devnull = open(os.devnull, 'a')

++    devnull = _EmptyWriter()
+ stdin = IOStream(sys.stdin, fallback=devnull)
+ stdout = IOStream(sys.stdout, fallback=devnull)
