Hello, I have installed the svn version of numpy. I have deleted all previous versions of and files related to numpy prior to installing. I also have tried reinstalling python from source. Regardless, when I try import numpy, I get the following:

undefined symbol: PyUnicodeUCS2_FromUnicode
This symbol is defined by Python when you build Python with 16-bit unicode support (as opposed to 32-bit) unicode support. Somehow numpy is picking up the 16-bit headers but you probably compiled with ucs4. NumPy supports both UCS2 and UCS4 builds. This looks to me like a Python header installation problem. There are probably some incorrect Python headers being picked up during compilation of NumPy. Can you double check which Python headers are being used (look at the -I lines when NumPy is being built). -Travis
