Conda: GData and http_interface

Question

I tried installing the latest version of GData using the latest version of conda and Anaconda :

Conda install gdata p>

It seems to have worked.

The following packages will be downloaded:

    package                    |            build
    ---------------------------|-----------------
    gdata-2.0.18               |           py27_0         765 KB
    python-2.7.7               |                0        10.0 MB
    ------------------------------------------------------------
                                           Total:        10.7 MB

However, when I try to do:

import gdata.spreadsheet.service

I get:

---> 33 import atom.http_interface
     34 import atom.url
     35 import atom.http

ImportError: No module named http_interface

Why? How can i use it?
