Ok, here is the patch [1]. Unfortunately, we can't just include USE_XZ 
into bsd.python.mk because this will affect *all* the ports, that define 
USE_PYTHON in their Makefile's. I can't think a way how to (nicely) 
apply USE_XZ to limited set of ports inside of bsd.python.mk. Using 
tar.xz instead of .tgz in ${PYTHON_DISTFILE} will not work on systems, 
that lacks xz in a base system and I dislike the duplication of USE_XZ 
internals in bsd.python.mk for them.

So this patch just replaces .tgz with ${EXTRACT_SUFX} and USE_XZ is used 
in individual python ports. I did some test builds of python and it's 
slaves (py-sqlite3, py-bdsdb, py-gdbm, py-tkinter) and everything seems 
fine. I also diffed all the four pairs tgz/tar.xz of each python version 
- and, as it was expected, their content is equal.

Any objections, suggestions etc?
