[boost] Boost.Python win32 build/link problem (boost_1_27_0)

From: Pål Frogner Hansen (pal_at_[hidden])

Question: To use boost.python, do I have to use the Jam thing? As there were dsw-workspaces included I hoped I could just use these.
Seemed to work, but I get linker errors.

I have tried with python 2.0.1, 2.2.0 and 2.2.1 installed. Also tried with vc6.0 and vc7.0. Building the example-project; both gives
me the error-message below.

What is wrong? Do I _need to_ use jam to build?

Thanx,
Pål Hansen (new to this!!)
