module std.regex

[Benji]

Hello,
when I try to run following code:

import std.stdio;
import std.net.curl;

void main()
{
	writeln("dlang.org");
}

I get following error:

Fatal Error while loading 
'/usr/lib/x86_64-linux-gnu/libphobos2.so.0.64':
	The module 'std.regex' is already defined in './maina'.
Segmentation fault (core dumped)

Somewhere I read that this should fix it:
- Make ModuleInfos immutable, which is something we should do 
anyhow.

But what are "ModuleInfos" ? Where I can find them and what 
exactly to do with them?
