DMD works just fine in a 32-bit chroot on my 64-bit Ubuntu. The Ubuntu 
forums have a thread (I think it's 
http://ubuntuforums.org/showthread.php?t=24575) explaining how to set 
this up. Be sure to install 32-bit gcc etc. in the chroot environment.

Looks like you're using the wrong version of Phobos with your gdmd. 
(Likely DMD's version)
I'm pretty sure you shouldn't need to specify include paths for phobos, 
GDC should know where gphobos (the version of Phobos it comes with) is 
installed.
