I'm not sure I agree with this part. For one thing, you can bet that "qmake" 
will *not* be Qt 5's for the next year or two, as people are still developing 
Qt 4 applications.

And like I said in another email, Qt 5's qmake is in an entirely different 
category from gcc, ruby, etc.

But I'm glad you brought python up!

Fedora$ ls -l /bin/python /bin/python?
lrwxrwxrwx. 1 root root     7 Aug  6 15:23 /bin/python -> python2
lrwxrwxrwx. 1 root root     9 Aug  6 15:23 /bin/python2 -> python2.7
-rwxr-xr-x. 3 root root 12888 Jun  7 22:36 /bin/python3

openSUSE$ ls -l /usr/bin/python /usr/bin/python?
lrwxrwxrwx 1 root root 9 Jul  8 03:03 /usr/bin/python -> python2.7
lrwxrwxrwx 1 root root 9 Jul  8 03:03 /usr/bin/python2 -> python2.7
lrwxrwxrwx 1 root root 9 Oct 19 10:38 /usr/bin/python3 -> python3.2

Debian$ ls -l /usr/bin/python /usr/bin/python?
lrwxrwxrwx 1 root root 9 May 14 11:03 /usr/bin/python -> python2.6

Ubuntu$
$ ls -l /usr/bin/python{,?}
lrwxrwxrwx 1 root root 9 Apr 17  2012 /usr/bin/python -> python2.7
lrwxrwxrwx 1 root root 9 Apr 17  2012 /usr/bin/python2 -> python2.7

As you can see, they are not symlinks to /etc/alternatives/. Those are non-
configurable symlinks. So even if Python 3 were installed on those Ubuntu and 
Debian, it still wouldn't have overwritten.

If you want to take python as precedence, then we conclude "qmake" is for Qt 4 
and we need to find a new name for Qt 5.
