[Nix-dev] Problems building installation CD on Debian etch x86_64

[Steve Roggenkamp]

I'm trying to build the installation CD on a Debian etch system 
(x86_64), but am running into a problem I can't debug.

I've downloaded and built the nix packaging system from Subversion:  
nix-0.12pre13257.  My nixpkgs system is from Subversion revision 13304 
and my nixos is revision 13254.

In the toplevel directory for nixos I type in the following command:

nix-build installer/cd-dvd/rescue-cd.nix

A short while later I get a long error message that has the last few lines:

I've spent quite a bit of time attempting to debug the situation.  The 
best I can figure out is the glibc-2.7-multi is attempting to build both 
the x86_64 and the i686 version to insure both sets of libraries.  As a 
newbie, I'm having difficulty in determining what I have to change in 
order to get this to build.

Any help would be appreciated.

TIA,
Steve
