[SciPy-User] Problems with 64-bit Scipy Stats

On my Windows 7, 64-bit AMD machine:

from scipy import stats produces:

Traceback (most recent call last):
  File "<pyshell#1>", line 1, in <module>
    from scipy import stats
  File "C:\Python26\lib\site-packages\scipy\stats\__init__.py", line 7, in <module>`
    from stats import *
  File "C:\Python26\lib\site-packages\scipy\stats\stats.py", line 202, in <module>
    import scipy.special as special
  File "C:\Python26\lib\site-packages\scipy\special\__init__.py", line 8, in <module>
    from basic import *
  File "C:\Python26\lib\site-packages\scipy\special\basic.py", line 6, in <module>
    from _cephes import *
ImportError: DLL load failed: The specified module could not be found.

Since Scipy's covariance function works outside of the stats package, for single variable linear regression I can create a work-around, using cov(y,x)/var(x) for beta and the correlation coefficient squared for R squared.  This is not ideal, however.
Any suggestion of other workarounds, or how to fix this?
