Okay,

It looks like what needs to be found are "libphobos2" and 
"libdruntime".  They can be found where ever your system puts lib 
files.  Windows (as far as I know) does not have a joined place 
for lib files so you need to look where dmd/ldc/etc installed 
itself.  On Linux lib files are generally put in `/usr/lib`.  
Ideally the hunting for lib files should be left to a build tool 
in order to be system agnostic.  In Cabal (Haskell's build tool) 
add "druntime" and "phobos2" to `extra-libraries`.
