David, I found part of the issue, I had some bogus env variables that I had to kill. The issue was the c was not compiling, but... I have a new error that has an odd name _aswfa_... Below is the error: Cheers, Brian In [4]: import scipy.signal --------------------------------------------------------------------------- ImportError Traceback (most recent call last) /Users/balarsen/<ipython console> in <module>() /Library/Python/2.6/site-packages/scipy/signal/__init__.py in <module>() 7 import sigtools 8 from waveforms import * ----> 9 from bsplines import * 10 from filter_design import * 11 from ltisys import * /Library/Python/2.6/site-packages/scipy/signal/bsplines.py in <module>() 2 ----> 3 import scipy.special 4 from numpy import logical_and, asarray, pi, zeros_like, \ 5 piecewise, array, arctan2, tan, zeros, arange, floor 6 from numpy.core.umath import sqrt, exp, greater, less, cos, add, sin, \ /Library/Python/2.6/site-packages/scipy/special/__init__.py in <module>() 6 #from special_version import special_version as __version__ 7 ----> 8 from basic import * 9 import specfun 10 import orthogonal /Library/Python/2.6/site-packages/scipy/special/basic.py in <module>() 6 7 from numpy import * ----> 8 from _cephes import * 9 import types 10 import specfun ImportError: dlopen(/Library/Python/2.6/site-packages/scipy/special/_cephes.so, 2): Symbol not found: _aswfa_ Referenced from: /Library/Python/2.6/site-packages/scipy/special/_cephes.so Expected in: flat namespace in /Library/Python/2.6/site-packages/scipy/special/_cephes.so -- Brian A.
