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

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?

seems that venv doesn't copy the standard Libs directory into the virtual
environment; if I do that by hand then I get a proper working virtual
environment. Also seems fairly half baked to change the name bin to Scripts, but
perhaps there's some windows centric reason for that even though the Scripts dir
ends up with a lot of dlls & pyds in it. I suppose that ps1 files are in fact
scripts.

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

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.
