Value.Error
Hi, 

on MacOs 10.9, 
with Python2.7.5
(ipython 2.2.0)
Numpy 1.8.2 and Pandas 0.14.1
(successfully) installed with "pip", 

I got the following when I try to import Pandas

```
ValueError: numpy.dtype has the wrong size, try recompiling
```

then, 
I installed pandas from github (uninstalling the pip packages before), 
and this time I got this one: 

```
ImportError: cannot import name hashtable
```

Any suggestion? 
I'm not interested in downgrading Pandas

best,
