[Boost-users] building 1.43 for iPhone

Hello, Few months ago I succesfully built 1.41 for iPhone, but it seems that the things changed since then. I'm trying to follow these recommendations (for 1.42): http://iphone.galloway.me.uk/2009/11/compiling-boost-for-the-iphone/ I define "iphone3.1.2" version in my user-config.jam, but bjam says: "feature.jam:485: in feature-validate-value-string from module feature error: 'iphone3.1.2' is not know value of feature <macosx-version>". Does it mean that the building system doesn't find user-config.jam? Thanks.
