I just installed Ubuntu 11 on my old laptop (works great) and pulled everything from git. Everything's fresh - compiler, druntime, phobos. Trying to make unittest for phobos I get:

Is the trunk broken?

You're dmd.conf file is missing the -lrt part of DFLAGS.

It looks like it's not linking with librt. dmd.conf needs to have -L-lrt in it. If it doesn't have it, then the default dmd.conf needs to be updated. I've just been using dmd 2.051, so I don't know what the state of dmd.conf in trunk is though. But it looks like it needs to be updated.
