Python is required, you cannot get rid of it.

AFAICT, this is caused by compiling the new xen-tools-4.7 port while still 
having the xen-tools-4.5 port installed. Due to the ports build environment 
the first path searched for libraries is /usr/local/lib instead of the one 
passed on the command line by the Xen build system.

My plate is completely full right now, so I cannot really pick this up. 
However if you manage to get the ports committed I should be able to add 
them to the xen-tools package.
