window 7 64bit BitNami Django stack install lxml module problem

Hello, dear all:

I want to use lxml module in BitNami django stack writing python codes.

After I install lxml by binary source provided by PYPI "https://pypi.python.org/pypi/lxml/3.1.2".

I can only find lxml in my standard python folder, which is C:\Python27\Lib\site-packages\lxml and can find it from windows command line python shell.

But I still can "not" use it and find it in django python codes, shows error with module "lxml" not found.

So how should I do to add this module in BitNami Django python?

Maybe add a system path with my normal python libs to BitNami Django search path?

Or should I re-install the whole thing into BitNami again, But how to do it?

BTW, my OS is Win7 64bit.

Any tips very welcomed.

Thank you.

Regards

Peter
