I think you can package also numpy with py2exe. Overall I think restricting to pure python is a very bad idea if you want to compete with Gauss. Even for a minimal translation of Gauss programs I need at least numpy and scipy, and statsmodels for the econometrics specific parts. linear algebra, optimization and special functions for distributions look like a minimum to me, and some scipy.signal for time series analysis, and more random numbers than in python`s standard library. Pure python will be slow for this and I doubt you will get anyone to switch from Gauss to pure python. Also, I haven`t seen yet a pure python matrix inverse, or linalg solver. If they want to write their own python programs for analysis and use python later on, then they are much better of getting a full python distribution, EPD, pythonxy or similar. Binary distributions are available and just one click or one command installs. And, for example, using Spyder would be a lot nicer and easier for writing scripts, that are equivalent to Gauss scripts, than using commandline tools. I fully agree with the objective of getting python/numpy/scipy tools to get economists, econometricians to switch from gauss or matlab, but to make it competitive we need enough supporting functions and we need the speed that some Monte Carlo simulations don`t take days instead of hours. I hope you are successful with getting economists or econ students to use python.
