Guix package steps

[Daniel Pimentel]

Hi guix,

I tried create new packages (ipcalc, nmap, xfburn and others) but 
without success.

My steps (based on talk GNU Guix packaging by Andreas Enge):
0. Git clone guix repository by savannah;
1. Copy gnu/package/indent.scm to mypackage.scm in this same folder;
2. Add module to gnu-system.am
3. Download mypackage;
4. Edit mypackage.scm and add hash, license and other information;
5. ./pre-inst-env guix build mypackage -K
6. Erro: bash: ./pre-inst-env: No such file or directory

But there is pre-inst-env.in only. The script pre-inst-env not exist in 
repository. So where is pre-inst-env?

Thanks for help and sorry for my noob question kkk.
