Would you send me a copy of your libcarddav config.log?

Sure! This is another reason I like to use the QuickBuild system when possible; it retains all that information for later analysis. You can get at a build log by expanding the package you are interested in, then clicking on the architecture you want to see build details for. Then click on buildlog.
Here is a direct link for the carddav package: https://quickbuild.pearsoncomputing.net/~trinity/+archive/trinity-builddeps/...
