I finally solved this after looking into the source tree. It turned out that 
after I re-compiled and installed Nix from source, the configuration 
directory (sysconfdir) is /usr/local/etc (a somewhat unconventional choice, 
if you ask me). It was /etc when I had installed Nix from the ubuntu 
package, but I recently upgraded my system to ubuntu trusty and there is no 
binary package for trusty yet, so I re-installed from source. Thus my 
existing entry for build-users-group in /etc/nix.conf was ignored.

BTW, I see that there are rpm specs in the sources. How can I create package 
for my system from the sources?

Cheers
Ben
