Trouble using FRED API in Python -- cannot load module

I am trying to use this API for the Federal Reserve Economic Data (FRED): https://github.com/zachwill/fred

I installed the three modules that the documentation said are required. I get this error:

import fred

Traceback (most recent call last):
  File "<pyshell#0>", line 1, in <module>
    import fred
  File "build\bdist.win32\egg\fred\__init__.py", line 1, in <module>
    # Dummy file to make this a package.
  File "build\bdist.win32\egg\fred\fred.py", line 21, in <module>
ImportError: cannot import name xml2dict

I then installed xml2dict and installed fred again. When I now do import xml2dict first and then import fred, I get the exact same error.

I had a hard time learning to install modules in Python but thought I finally had it figured out. I can't seem to find what I am doing wrong here though and could use some help. Thanks!

For Zach: This is the problem I'm currently having:

Traceback (most recent call last):
  File "<pyshell#3>", line 1, in <module>
    fred.series('GNPCA')
  File "build\bdist.win32\egg\fred\api.py", line 90, in series
    return Fred().series(path, **kwargs)
  File "build\bdist.win32\egg\fred\core.py", line 100, in series
    return self.get('series', path, **kwargs)
  File "build\bdist.win32\egg\fred\core.py", line 36, in get
    request = requests.get(url, params=params)
  File "C:\Python26\lib\site-packages\requests-0.13.2-py2.6.egg\requests\api.py", line 54, in get
    return request('get', url, **kwargs)
  File "C:\Python26\lib\site-packages\requests-0.13.2-py2.6.egg\requests\safe_mode.py", line 37,     in wrapped

    raise ConnectionError(e)

I'm the developer of the fred package. This is completely my fault — I had the setup.py file incorrectly configured, and I just pushed an update that should take care of this issue. Sorry for the confusion!

Tips on Installing modules in general:

What's generally easiest is to use pip or easy_install (or a binary installer if available) - that way all you need to do is easy_install fred and everything will automatically be downloaded that's required (as long as it's been configured properly).

Check out setuptools at http://pypi.python.org/pypi/setuptools and install that for your appropriate OS version. You will then get a command called easy_install which will be installed in a certain location depending on your OS/setup (the docs do mention where though). [You can also easy_install pip as pip is effectively easy_install's successor]

Then hopefully, all you need to do is easy_install fred (which will automatically find at http://pypi.python.org/pypi/fred), and it will download the latest version and all dependencies for you. Fire up your interpreter and import fred should "just work".
