Autoconf Autoheader nonsense

In ubuntu (and may be also in debian) autconf and autoheader 2.50 packages actually install version 2.61.
and version 2.13 is also installed by default

Now the problem is
If you are using kde supplied Makefile.cvs (www.taskjuggler.org comes with it) it will complain that autoconf is of version 2.13 and it needs >2.53

This Makefile is only for the CVS repository
This will be deleted before making the distribution

*** YOU'RE USING Autoconf version 2.13.
*** KDE requires a utoconf 2.53 or newer

The thing is /usr/bin/autoconf is actually a wrapper sh script which picks which version to chose by using some silly huristics. (see man autoconf)

The huristic is something like if configure.ac exists in the directory you are running in it choses 2.61 else 2.13.
So to make kde cvs makefile work i just did following

sudo mv /usr/bin/autoconf /usr/bin/autoconf.bak
sudo ln -s /usr/bin/autoconf2.50 /usr/bin/autoconf
sudo mv /usr/bin/autoheader /usr/bin/autoheader.bak

sudo ln -s /usr/bin/autoheader2.50 /usr/bin/autoheader

Saves my day, use at your own risk......

I am putting here in hopes the google picks it up saves somebody else's few minutes of frustration.
