That's because you are running the apple installed python. You need to install the python_select port and then type

	sudo python_select python24

That will run the (older) python 2.4 from Macports. Is there a reason you want an older version of python? I run the py26-numpy port successfully with python 2.6. 

$ ipython
Python 2.6.5 (r265:79063, Jul  8 2010, 16:24:47) 
Type "copyright", "credits" or "license" for more information.

In [1]: import numpy

In [2]: numpy.__version__
Out[2]: '1.4.1'
