Trying to build git-head

[SanskritFritz <sanskritfritz gmail com>]

I try to build kupfer from the git, based on this AUR script: https://aur.archlinux.org/packages.php?ID=43459

This is how I modified it (basically just threw outdated waf out, installing it separately as makedepend):


> ... [snip]
> makedepends=('git' 'python2-waf')
> ... [snip]
>   #
>   # BUILD HERE
>   #
>
>   # Python2 fixes
>   export PYTHON="/usr/bin/python2"
>
>   sed \
>         -e "s_env python_&2_" \
>         -e "s_bin/python_&2_" \
>         -i `grep -rlE "(env python|bin/python)" .`
>
>   waf configure --prefix=/usr
>   waf
> }
>
> package() {
>   cd "$srcdir/$_gitname-build"
>
>   waf install -f --destdir="$pkgdir/"
> }

Now when I run makepkg, waf complains like this:

What is this xml2po, and is it really necessary? Sadly there is no package for it in the aur.
