This almost worked (at least, it appears to).  I got the module to 
build and install using VS 2005.  It works fine if I run python from 
the directory where I built the extension.  However, if you go to any 
other directory, run python, and try to import the module, I get the 
following error:

ImportError: dynamic module does not define init function (initsasSQL)

Why would it work from one directory, but not another?
