What "same reason" ?

So you mean that all those Python packages are not needed on the host,
but because the build system is bogus and checks their presence on the
host, we have to have them as dependencies ?

So indeed, there's a macro in cmake/Modules/PythonModule.cmake that is
used to check for Mako, Numpy and Six, and it works by running the host
Python. I imagine they are in fact not needed on the host, and this
macro needs to be adjusted. However, I'm not sure what's the right way
to test if a *target* Python module is available.

Maybe Yegor can help on this ? :-)
