try to compile this program from std.net.curl

import std.net.curl, std.stdio;

void main()
{
    auto range1 = byLineAsync("www.google.com");
    auto range2 = byLineAsync("www.wikipedia.org");
    foreach (line; byLineAsync("dlang.org"))
        writeln(line);

    foreach (line; range1) writeln(line);
    foreach (line; range2) writeln(line);
}
I compile this program like this.

$ dmd internet.d -ofinternet
or

dmd -I/usr/include/dmd/phobos -L-l:libcurl.so.4.2.0 internet.d -ofinternet
The program compiles fine but it throws an exception.
