[Nix-dev] is there something like unsafeImpureEnvVars?

Ok, I now have

  build-use-chroot = true

in my /etc/nix/nix.conf. Now, my build fails with this strange error:

building /nix/store/y57pn9yk7r9j06nqfkyd4b1h5p8gfdzr-epics-
base-3.14.12.2.1/configure/CONFIG_ENV
make[2]: /bin/sh: Command not found

I _did_ run the patchShebangs function on my sources before building. I 
verified that this actually worked by using the -K option to nix-build, then 
looked at the build directory:

base-3.14.12.2.1.drv-8 
ben at sarun[1]: /tmp/nix-build-epics-base-3.14.12.2.1.drv-8 > rgrep '/bin/sh'

bash-4.2-p42/bin/sh

So everything in my sources is patched to use stuff from /nix/store (I 
checked that the path exists and is executable) and still it complains about 
some /bin/sh missing?
