It seems it tries to link against a wrong Phobos version. Try 
running dmd with the `-v`, it will output how it invokes the 
linker (usually starting with "cc"). Maybe you have to adjust 
your dmd.conf, or create one. I like to place a link to dmd in my 
~/bin directory (which is in $PATH), and put a dmd.conf next to 
it, so it's picked up automatically:
