very weird pandas behavior

[ryguy7272]

I downloaded pandas and put it in my python directory, then, at the C-prompt, I ran this:
"pip install pandas"

It looks like everything downloaded and installed fine.  Great.

Now, in Python Shell, I enter this:
import pandas as pd

I get this error.  
Traceback (most recent call last):
  File "<pyshell#19>", line 1, in <module>
    import pandas as pd
ImportError: No module named pandas


Any idea what I'm doing wrong?
