Here is a Phobos translation:

import std.socket;

void main() {
     Socket server = new TcpSocket();
     server.setOption(SocketOptionLevel.SOCKET, SocketOption.REUSEADDR, 
true);
     server.bind(new InternetAddress(8080));
     server.listen(1);

     while(true) {
         Socket client = server.accept();

         char[1024] buffer;
         auto received = client.receive(buffer);

         writefln("The client said:\n%s", buffer[0.. received]);

         enum header =
             "HTTP/1.0 200 OK\nContent-Type: text/html; charset=utf-8\n\n";

         string response = header ~ "Hello World!\n";
         client.send(response);

         client.shutdown(SocketShutdown.BOTH);
         client.close();
     }

Not quite the same - the original used a Unix domain socket. I 
*think* if you replace that line with a UnixAddress:

http://dlang.org/phobos/std_socket.html#UnixAddress

It will do the trick. (I say *think* because I've never actually 
used a unix socket with D, so I'm not entirely sure.)

It won't work. (This is why my project uses IP sockets for local 
communication, even on Linux)

Meaning that domain/Unix sockets aren't available at all in D (or 
need to be done through C calls directly)?

That has already been fixed in the version of Phobos on Github 
(I've marked it as fixed now, didn't know about that issue on 
bugzilla before).

In the example you give, but I receive this error during 
compilation.

Your dmd installation is broken. Please tell how have you set it

To help dicebot and others to help you it would be useful to copy 
the output of the following two commands:

 cat /etc/dmd.conf

 find /usr -name 'libphobos2*'

(Please note the *single* ticks (rather than ") to not have your 
shell resolve it. Also note that probably /usr/lib would be more 
efficient as search path but using /usr can also catch exotic 
cases like /usr/share).

If your installation is OK you will find the paths told by the 
find command to match those in /etc/dmd.conf.

Here is an example of a working installation:

$ find /usr -name 'libphobos2*'
/usr/lib/x86_64-linux-gnu/libphobos2.so
/usr/lib/x86_64-linux-gnu/libphobos2.a
/usr/lib/i386-linux-gnu/libphobos2.so
/usr/lib/i386-linux-gnu/libphobos2.a
/usr/lib/i386-linux-gnu/libphobos2.so.0.2
---------------

$ cat /etc/dmd.conf
// ... some comment lines ..

[Environment]

DFLAGS=-I/usr/include/dmd/phobos 
-I/usr/include/dmd/druntime/import -L-L/usr/lib/i386-linux-gnu

It's just a spambot scouring for keywords (socket programming).
