Unable to get Phobos working on Ubuntu x64 (Oneiric)

[Kiith-Sa]

I've just installed a new system - Ubuntu 11.10 beta x64 and can't get 
dmd/phobos 2.055 to work.

When I try to compile file hello.d with the following content: 

import std.stdio;

void main()
{
    writeln("Hello World!");
}


I get this error:

/usr/lib/gcc/x86_64-linux-
gnu/4.6.1/../../../../lib/libphobos2.a(datetime_48b_1ec.o): In function 
`_D3std8datetime5Clock11currStdTimeFNdNeZl':

Nothing else using Phobos compiles either.

I've seen previous related threads. Tried -L-lrt, didn't work.
I tried the .deb package for Ubuntu, the binaries shipped
in the source archive, as well as compiling Phobos myself (removing 
DMD/Phobos every time to make sure no files persisted), but nothing helped.


Has anyone encountered this problem? Did anyone get it to work on Ubuntu 
(especially 11.10)?
