My point is that in the failed cases /usr/bin/python was not used, otherwise 
the build would have succeeded. It seems that cmake uses the python 
interpreter it detects to run the scripts. So patching the scripts doesn't 
change anything by itself, IIUC.

Related to this, what do you thing about changing the host python requirement 
in the manual?
