Summary: sys.version[:3] gives incorrect version

Initial Comment:

sys.version[:3] is used in several places [*] for
Python version and in most cases it is OK.
However, when Python is build/installed, say, with
  make all install VERSION=2.2.2
then sys.version[:3] does not represent Python version
correctly anymore. For example, the path to Python Lib
is then
  <prefix>/lib/python2.2.2/
but e.g. distutils finds it as
  <prefix>/lib/python2.2/
which obviously causes either an exception or a silent
incorrect behaviour [**] when trying to use distutils.

Note about fix: I don't have it but simply replacing
sys.version[:3] with
sys.version.split()[0] will not work.

Best regards, Pearu

[*] Running
  grep  "sys.version\[:3\]" {*,*/*,*/*/*}.py
in the Python Lib tree shows 8 matches for Python 2.2.2.

[**] .. e.g. when one has other Python installed with
VERSION=2.2

I would suggest that 'make all install VERSION=2.2.2' is not
supported, so this does not need to be fixed.
