I am running ActiveState Python 3.2, and getting this cryptic error:
D:\code>python
ActivePython 3.2.1.2 (ActiveState Software Inc.) based on

>>> import numpy as np

>>> be = np.linalg.lstsq(x,y)
MKL ERROR: Parameter 5 was incorrect on entry to DGELSD

Does anyone know what might be going on?

NumPy doesn't depend on any other Python packages, however, it does depend on an accelerated linear algebra library - typically Intel MKL or OpenBLAS.
So numpy-mkl just means a version of numpy compiled against the MKL fortran library. Probably whichever version of numpy you previously had installed was somehow broken, and couldn't find the libraries it needed. Follow this answer to receive notifications.
mkl-service - Python package for run-time control of Intel(R) Math Kernel Library.
Intel MKL may be used with the GCC compilers installed on Apocrita. The Intel MKL Link Line Advisor tool can be used to determine the required compiler and link flags to access the package. The variable MKLROOT , referred to in the advisor output, should be set to the directory where the version of MKL is installed.
There seems to be no answer to that. The best I can do is provide the link to my bug report to ActiveState which is now being looked into.
