Yo Asus, you're a bit slow receiving a response from the list for this issue. Apologies!
That error message - "cannot auto-call a function..." - this occurs when when you call a Nix function but don't supply a requested value. Here's [1] a page on the NixOS wiki where I'm trying to gather common error messages. This one is on that list. That page links to this [2] older email thread from someone with a similar issue. In Nix, functions can take "named arguments". Here's a page [3] which describes this concept implemented in C#. In your case, your package's function signature includes a whole set of arguments { stdenv, fetchurl, pkgconfig, libsoup, webkit, gtk, glib_networking, gsettings_desktop_schemas, makeWrapper }: Here's where to wiggle the code to fix it. If you want to call this function, a value must be specified for each parameter. luakit = callPackage ../applications/networking/browsers/luakit { inherit stdenv; # Add some more arguments here. Check other packages for examples. inherit (gnome) libsoup; webkit = webkit_gtk2; }; Now, IIRC, the `callPackage` function should resolve most of these arguments automatically, so we shouldn't need to give `stdenv` a value. So, this is why I can't give you an exact solution. Take a bit to read the source code a bit, here [4], and read backwards to see how that is implemented. Hopefully there's some comments. Apologies for my laziness to completely solve the problem for you!
