Build openpli4 on archlinux

Hi at all, i'm trying to compile my own openpli 4.0 image for vusolo2. My OS is archlinux x86_64 fully updated. I follow these steps

mkdir ~/bin
ln -s /usr/bin/python2 ~/bin/python
export PATH=~/bin:$PATH

a trick to use python 2 instead of python 3. More info https://wiki.archlinux.org/index.php/Python

Then

mkdir openpli_4.0
cd openpli_4.0/
mkdir sources
git clone git://git.code.sf.net/p/openpli/openpli-oe-core
cd openpli-oe-core
make
MACHINE=vusolo2 make image

but

Build Configuration:
BB_VERSION        = "1.21.1"

Makefile:74: set di istruzioni per l'obiettivo "image" non riuscito
make: *** [image] Errore 1

My questions are:

-is it a problem related to python (v2.7.6)?

-is it a problem related to archlinux?

-is it a problem related to openpli packages?

Could someone help me?

Thanks in advance
