AttributeError: Cannot use pandas from a script file
I am using the Anaconda distribution of Pandas on a Mac.

I am able to use the Pandas module from within the python console, but am unable to use it from within a script file. i.e. when I run a script that imports the pandas module, then I get an attribute error.

For example, this:

```
import pandas as pd
df = pd.DataFrame()
```

will give me this error:

```
Traceback (most recent call last):
File "/Path/To/File/file.py", line 1, in <module>
import pandas as pd
File "/Path/To/File/file.py", line 2, in <module>
df = pd.DataFrame()
AttributeError: 'module' object has no attribute 'DataFrame'
```

And similarly, this:

```
import pandas as pd
df = pd.Series()
```

will give me this error:

```
Traceback (most recent call last):
File "/Path/To/File/file.py", line 1, in <module>
import pandas as pd
File "/Path/To/File/file.py", line 2, in <module>
sr = pd.Series()
AttributeError: 'module' object has no attribute 'Series'
```

Yet both of these work fine from the console.

I've tried uninstalling and re-installing from anaconda, pip, and from the github source, to no avail.

Thanks.
