Two things I can think of:

1) If you use bud, it will compile all necessary files.  No need to link  
with any libraries.  Bud recurses the Derelict directories (as inferred  
 from the import statements in your module), and manages the compiling and  
linking of the individual modules needed for the build.  So you can remove  
all the library commands line args.  An include directory to the derelict  
path will still be necessary.

2) You probably have to pass the "-op" flag to dmd which makes sure that  
object files stay put in the same directory as the source.  By default all  
object files get stored in the working directory which can cause annoying  
problems later when gcc thinks they should be in the source directory.  So  
try adding "-op" to your commandline.
