It is safer to use "make altinstall" (look at "Installing multiple
versions" in Python's README file).  Altinstall does not create a
"python" executable, but only a file named with explicit version data,
e.g. "python3.1".

Even if one is careful to manage installation prefixes so different
versions of Python are installed in different places (/usr/bin and
/usr/local/bin, for example), if something named "python" is in both
locations, this invites confusion.
