Yeah. Make sure that your dmd.conf is up-to-date. There are a number of changes in it with the most recent release - not only the addition of librt, but the lib directories were changed as well. So, everyone should either use the dmd.conf that comes in the release or make sure that the dmd.conf that they use is based on that dmd.conf. You're going to run into problems otherwise. - Jonathan M Davis
