Trying to upgrade Django using pip on CentOS results in segmentation fault

Hello,

I have a Linux CentOS 6.7 installation on a VM. A few months ago, I had - 
compiled and installed Python 2.7.8 on it - installed virtualenv-13.1.2 in 
/usr/lib/python2.7/site-packages - installed Django 1.7 inside the 
virtualenv. - compiled and installed mod_wsgi 4.4.21 and used it to deploy 
Django on Apache

I have been using this over the last few months with no issues.

I am now trying to upgrade to Django 1.8.8. I activated the virtualenv and 
then executed the following command, but it encounters a segmentation fault 
each time.

$pip2.7 install --upgrade django==1.8.8
Collecting django==1.8.8

If I preface the command with sudo, there is no segmentation fault, but it 
does not proceed to install the new version of Django at all.

Output of verbose option given below 

pip2.7 install --upgrade django==1.8.8 -v

p2.7 install -r 
requirements/production.txt  --no-cache-dir

This worked fine, and I was able to upgrade the packages in my old 
virtualenv as well as do a fresh install in the new one.

Whew!!

Regards,
Tanuka
