I'm trying to get Boost built with VS 2008. An earlier post recommended using the trunk build, but I received the following errors.

...failed msvc.link.dll bin.v2\libs\signals\build\msvc-9.0\release\threading-mul

Also, I would like to use STLPort (5.2). How do I specify that? I've tried creating a user-config.jam file, but I'm not sure that is correct way.  Thanks.
