Linking D Runtime

[Jonathan Levi via Digitalmars-d-learn]

I am trying to find the D runtime/standard-library 
object(.o)/library(.a) files inorder to link them with some 
foreign code (Haskell as it happens).

I am writing a program in Haskell but want to use D for some of 
the imperative style logic.  I expect to have a large section of 
code in D so I want to take advantage of the D runtime, garbage 
collector, and standard libraries.

I found several discussions on getting the D runtime going, so I 
expect that to be easy, but (obviously) I get link errors when I 
do not have it to link.

What is the advised way to get the object(.o)/library(.a) files 
for the D runtime and standard library?

Thanks!
