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

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

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

This is my configuration file:

$ cat myvenv/pyvenv.cfg
home = /usr/local/bin
include-system-site-packages = false
version = 3.4.0

In this case (default), the site-package directory is not included in
the PYTHONPATH. If you want to include it, set:

include-system-site-packages = true

include-system-site-packages = true

this has nothing to do with site-packages so far as I can tell. It seems that
even if you have a compiler you need to copy the python-3.3\Libs folder into the
environment so that distutils can set up the load command properly.
