Hi Eelco Dolstra,

if this really is an issue I'll help eliminating those lines.
Mostly I used this style for very simple small packages.
I'd like to use some batch processing then maybe writing some helper
scripts doing everything in one go.

Which is the new way to pass packages to derivation default.nix files?

foo = (import ...) ( pkgs // python = python24; );

?

I dislike listing deps more than once that's why I used the with style
that often..

How to handle things like 

  gajim = builderDefsPackage (import ../applications/networking/instant-messengers/gajim) {
  [..]
    inherit (gnome) gtk libglade;
    inherit (xlibs) libXScrnSaver libXt xproto libXext xextproto libX11 scrnsaverproto;
  [..]
  };


  buildInputs = with a; [
    python pyGtkGlade gtk perl intltool dbus gettext
    pkgconfig makeWrapper libglade pyopenssl libXScrnSaver
    libXt xproto libXext xextproto libX11 gtkspell aspell
    scrnsaverproto pycrypto pythonDBus pythonSexy 
    docutils
  ];

?

Note passing of those attrs gtk, libglade, libX*.
