It means that it can't find the source code for druntime. Likely, your dmd.conf 
is messed up or it's in the wrong place. There should be a dmd.conf file next 
to the dmd binary. It defaults to something like this

[Environment]

DFLAGS=-I%@P%/../../src/phobos -I%@P%/../../src/druntime/import -L-
L%@P%/../lib64 -L-L%@P%/../lib32 -L--no-warn-search-mismatch -L--export-
dynamic -L-lrt

Assuming that you just unzipped the zip file and used that, then everything 
should be in the right place. Presumably, the same goes for the deb or rpm 
packages if you used those. If you moved any of it around yourself, then 
you're probably going to have to make sure that you have dmd.conf next to the 
dmd binary and that it actually sets DFLAGS such that it points to where the 
source for druntime and Phobos is as well as where libphobos.a is.
