The manual, under "Mandatory packages", currently lists "python (version 2.6 
or 2.7)". Should we change that to "python (version 2.6 or any later)"?

My interpretation of the cmake log is that cmake uses the python interpreter 
it detects to run the scripts. In the failed cases cmake detected host-python3 
because host-python3 happened to build before qpid-proton. cmake did not use 
the distro installed host python even though it's python2 (most likely). So 
I'm not sure patching the scripts is necessary.
