Problems with s3cmd utility

On one of the cloud instances, I was trying to upload a large file to a S3 bucket and I had to install s3cmd utility. Going with the approach of getting the latest and greatest did not serve well. I downloaded the 1.5.0 rc1 version from the link - s3cmd and unzipped it into a folder. Subsequently, I ran the install command from the installation director

$ sudo python setup.py install

the above seemed to work fine. However, when I tried to run "s3cmd --configure", I got the below error:-

***********

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

    An unexpected error has occurred.

  Please try reproducing the error using

  the latest s3cmd code from the git master

  branch found at:

    https://github.com/s3tools/s3cmd

  If the error persists, please report the

  following lines (removing any private

  info as necessary) to:

   s3tools-bugs@lists.sourceforge.net

On their github, it appears that other have run into the issue without a proper resolution. So later had to go back to the option of installing through package manager on RHEL instance to make it work.

$cd /etc/yum.repos.d/

$wget http://s3tools.org/repo/RHEL_6/s3tools.repo

$sudo yum install s3cmd

$s3cmd --configure
