Did you try it with -fPIC instead of -fpic like the error message suggests?
(Or if that doesn't work, perhaps try recompiling libgphobos with that 
option; I'm not sure what exactly the message means)

Yes, tried that.  The problem is we have to have a shared libgphobos.  On
i386 linux, it was legal to link non-pic code into a shared library.  This
is not legal on x86_64 (and, I think, most other arch's).

You don't have to have a /shared/ libgphobos, but you do have to have a 
-fPIC libgphobos.
