Thanks - I was wondering if layers had something to do with it.

> Instead of setting P_V 2.40 only for that single project which needs that newer libsoup, you need to set P_V to 2.38 for every other project which is using your layer.

I can work with that - the layer is being used to up-rev various recipes for bug fixes (e.g. bash) and to add later versions of things like gstreamer. It would be nice if the default was "keep it as is" with DP set to -1, but I think I'll need to create a distro to get that behaviour.

From the link it looks as if layer priority may also be important, so I'll have a play with that when the current build finishes...
