Problem in GNU radio installation on fedora 17


Hi,
I want to install GNU radio on fedora 17. I am facing following problems. I used following command as given in the gnuradio.org
wget http://www.sbrac.org/files/build-gnuradio && chmod a+x ./build-gnuradio && ./build-gnuradio

[root@localhost gr]# wget http://www.sbrac.org/files/build-gnuradio && chmod a+x ./build-gnuradio && ./build-gnuradio

Please run this script as an ordinary user
it will acquire root privileges as it needs them via "sudo".

[gr@localhost ~]$ ./build-gnuradio
This script will install Gnu Radio from current GIT sources
You will require Internet access from the computer on which this
script runs. You will also require SUDO access. You will require
approximately 500MB of free disk space to perform the build.

This script will, as a side-effect, remove any existing Gnu Radio
installation that was installed from your Linux distribution packages.
It must do this to prevent problems due to interference between
a linux-distribution-installed Gnu Radio/UHD and one installed from GIT source.

The whole process may take up to two hours to complete, depending on the
capabilities of your system.

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
NOTE: if you run into problems while running this script, you can re-run it with
the --verbose option to produce lots of diagnostic output to help debug problems.
This script has been written to anticipate some of the more common problems one might
encounter building ANY large, complex software package. But it is not pefect, and
there are certainly some situations it could encounter that it cannot deal with
gracefully. Altering the system configuration from something reasonably standard,
removing parts of the filesystem, moving system libraries around arbitrarily, etc,
it likely cannot cope with. It is just a script. It isn't intuitive or artificially
intelligent. It tries to make life a little easier for you, but at the end of the day
if it runs into trouble, a certain amount of knowledge on your part about
system configuration and idiosyncrasies will inevitably be necessary.


Proceed?y
Starting all functions at: Fri Dec 21 18:17:43 IST 2012
SUDO privileges are required
Do you have SUDO privileges?y
Continuing with script
[sudo] password for gr:
gr is not in the sudoers file. This incident will be reported.

Please let me know whether I am doing it rightly and what should I do for "gr is not in the sudoers file. This incident will be reported".

Regards
Fabe

Resolved using following command
echo 'gr ALL=(ALL) ALL' >> /etc/sudoers

Now it is showing
Installing prequisites...
What may be the problem.

fedora by default dose NOT use "sudo"
it was deemed a unneeded security risk

but
if you need it
you will need to manually set it up ( it is turned off by default )
see the fedora documents
http://docs.fedoraproject.org/en-US/index.html
or
http://www.server-world.info/en/note...itial_conf&f=7

but mind you
if you give root access to EVERYONE
that might also include people that YOU do not want to have that access
( like a remote system cracker )
so use caution
