* Dirty interim hack to make header file dependency determination

Browse source 
reliable (if somewhat inefficient): make the current time an
  attribute of the derivation.  Thus, every call to `nix-build' will
  cause the find-includes derivation to be re-done (but not the actual
  compilations if that's not necessary!).  I added a `curTime' primop
  to do this.
