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.
