For your information, it seems that the egg recipe is downloading wheels by default. When the wheels is specific to x86_64 architecture, it can't be used on other architectures. Hence for those wheels, I manually fetch the sources of the egg.

It would be better to make the egg recipe prefer the source instead of the wheel but I don't really know how to do that.

I don't know a way to make the egg recipe force downloading source, but something like this, downloading the source packages ourselves and putting it where buildout will find them, seems a good workaround.

Can we assume pip command will be present or do we need to install explicitly ?

Unfortunately, I needed to move away from pip (see 055ffef4)

Can we assume pip command will be present or do we need to install explicitly ?

I'm assuming this runs on a correctly configured machine with everything installed. Anyway the script will fail if it's not installed and operator can do the installation.
