Yes, just add (host-python is python2; host-python3 is, well, python3):

    XEN_DEPENDENCIES = host-python

Then it depends.

If Xen can be told what python to use, then that's easy (e.g.:
--with-python=python2 or whatever else...)

However, if you can't tell Xen what python to use, then this is a bit
more involved.

See how it was solved for example for qt5webkit:

    package/qt5webkit: needs host-python

    The Qt5Webkit build system hard-codes calls to 'python', but only really
    supports python2.

    We fix that similarly as we did in nodejs, by adding a python->python2
    symlink early in the PATH when configuring/building Qt5Webkit, and
    adding host-python in the dependency list.

    [--SNIP--]

This is commit ac16793eaaabfced0312420759e3a66cdaa1ea8e and you can get
some inspiration from it.

Thomas, we now have a few packages that need this hack. Should we try to
move those hacks into the pkg infra (obviously not for 2016.08)?

Cordialement,
Yann E. MORIN.
