I can understand what you intend to do but the general problem is that there are two versions of python available.How can I install Python packages that will work with the Python that came with Zen blue.
The first one is 'normal Python' which runs under 'native or unmanaged code'.
The second one is 'IronPython' which is not native but managed code and relies on .Net.
As Zen blue is build with .Net IronPython is the language that interfaces with Zen.
As 'normal Python' and IronPython are embedded in 'different worlds' it is normally not possible to use one package or library in both versions. The only exception I know is when a package comes as 'source code'. Then it is very likely that it works in both versions of python.
I hope this helps to clarifiy the situation.
