python33.lib missing for build_ext in venv environment

[Robin Becker]

I'm trying to port reportlab extensions to Python 3.3. On windows I get a 
missing library error when trying to build/install the trial reportlab in a 
virtual environment eg

> C:\code\hg-repos\reportlab>\python33\python -m venv tpy33
> C:\code\hg-repos\reportlab>tpy33\Scripts\activate
> (tpy33) C:\code\hg-repos\reportlab>rm -r build
>
> (tpy33) C:\code\hg-repos\reportlab>python setup.py build_ext

this doesn't happen if I run the installed Python-3.3 directly eg

> (tpy33) C:\code\hg-repos\reportlab>tpy33\Scripts\deactivate.bat
> C:\code\hg-repos\reportlab>c:\python33\python setup.py build_ext

is this a bug or some misconfiguration; should I be using virtualenv?
