wheel error pip install egenix-mxodbc

gistfile1.txt

I've seen this on both Linux & Windows while using pip install as well as upgrade (-U option).
The installation works for my virtualenv, but there is a build error for creating wheels.

(zopish) C:\Users\sallen\env\zopish\Lib>pip install -U egenix-mxodbc
