autogen.sh and configure errors

[Arthur Miller]

I just pulled Emacs and got some configure errors. So I removed my old
sources, cloned new from Savannah and tried to configure again and I am
getting same errors:

Checking for autoconf (need at least version ) ... unable to check

Building Emacs from the repository requires the following specialized programs:
autoconf (minimum version )

Your system seems to be missing the following tool(s):
autoconf (unable to check)

If you think you have the required tools, please add them to your PATH
and re-run this script.

Otherwise, please try installing them.
On systems using rpm and yum, try: "yum install PACKAGE"
On systems using dpkg and apt, try: "apt-get install PACKAGE"
Then re-run this script.

If you do not have permission to do this, or if the version provided
by your system is too old, it is normally straightforward to build
these packages from source.  You can find the sources at:

https://ftp.gnu.org/gnu/PACKAGE/

Download the package (make sure you get at least the minimum version
listed above), extract it using tar, then run configure, make,
make install.  Add the installation directory to your PATH and re-run
this script.

If you know that the required versions are in your PATH, but this
script has made an error, then you can simply re-run this script with
the --no-check option.

Please report any problems with this script to bug-gnu-emacs@gnu.org .

As seen when I try to change to native-comp branch it says configure.ac is
changed; I didn't change it.

Finally after stashing and runing autoge.sh, I get followin when I run
configure:

My system or what am I doing wrong? I see nobody else complains so I
guess it is something on my side :-).
