MadAnalysis5: Missing Numpy and couldn't install it

Hi So I am trying to run MadAnalysis5.
As I run it for the first time, the program keeps complaining that numpy is missing and gives me the following error:

Checking mandatory packages:
     - python [OK]
     - python library: numpy [FAILURE]
 ** ERROR: The python library 'numpy' is not found. Please install it with the following command line:
 ** ERROR: apt-get install python-numpy

I tried the "sudo apt-get install python-numpy" it keeps telling me that it doesn't work, it is something that is very similar to the error described here:
http://mrprajesh.blogspot.hk/2009/11/e-couldnt-find-package-on-apt-get.html
but I couldn't solve it the same way as I am using an OSX system.

I therefore switched to using home-brew to install the program.
I did this:
1. Go to terminal:
2. $brew search numpy
3. (look at the file generated. found a file called: homebrew/python/numpy)
4. $brew install /homebrew/python/numpy

It is installed successfully. but when I go back to running MA5, it give me the exact same error claiming that The python library 'numpy' is not found.

I am using Python 2.7 and OSX 10.9.5 if it makes a difference.
Thanks in advance for your help!
