Shared Object with DMD v2.031

[teo]

I have difficulties creating a Shared Object (.so) with D. Is it 
possible? Can I use classes defined in the library from the executable?

Here is my library file:
module test; // file "test.d"
export int testMe() { return 1; }
export class Test
{
    private int n;
    this(int i) { n = i; }
    int get() { return n; }
}

I compile like shown below:
$ dmd -fPIC -c test.d
$ gcc -shared -o libtest.so test.o

I have now a "libtest.so" and
$ nm libtest.so
shows following:

00000860 t

         U _D14TypeInfo_Class6__vtblZ

00000820 t frame_dummy


And this is the program:
module main; // file "prog.d"
import std.stdio;
import test;
void main()
{
   writefln("testMe: %d", testMe());
   writefln("Test class: %d", (new Test(3)).get());
}

I compile it with:
$ dmd prog.d -L-L`pwd` -L-ltest

And get:
/usr/bin/ld: dynamic variable `_D4test4Test7__ClassZ' is zero size
/usr/bin/ld: prog.o(.text._Dmain+0x26): unresolvable R_386_32 relocation 
against symbol `_D4test4Test7__ClassZ'
/usr/bin/ld: final link failed: Nonrepresentable section on output
collect2: ld returned 1 exit status
--- errorlevel 1

Please note that "_D4test4Test7__ClassZ" is defined in the library.

BTW compiling with following works:
$ dmd test.d prog.d
