# Install development tools and some misc. necessary packages
yum -y groupinstall "Development tools"

# Alias shasum to == sha1sum (will prevent some people's scripts from breaking)
echo 'alias shasum="sha1sum"' >> $HOME/.bashrc
# Install Python 2.7.4 (do NOT remove 2.6, by the way)
wget --no-check-certificate http://www.python.org/ftp/python/2.7.4/Python-2.7.4.tar.bz2
tar xf Python-2.7.4.tar.bz2 
cd Python-2.7.4
./configure --prefix=/usr/local 
make && make altinstall
# Install virtualenv and virtualenvwrapper
# Once you make your first virtualenv, you'll have 'pip' in there.
# I got bitten by trying to install a system-wide (i.e. Python 2.6) version of pip;
# it was clobbering my access to pip from within virtualenvs, and it was frustrating.
# So these commands will install virtualenv/virtualenvwrapper the old school way,
# just so you can make yourself a virtualenv, with pip, and then do everything Python-related
# that you need to do, from in there.
wget --no-check-certificate https://pypi.python.org/packages/source/v/virtualenv/virtualenv-1.9.1.tar.gz#md5=07e09df0adfca0b2d487e39a4bf2270a
tar -xvzf virtualenv-1.9.1.tar.gz 
python virtualenv-1.9.1/setup.py install
wget --no-check-certificate https://pypi.python.org/packages/source/v/virtualenvwrapper/virtualenvwrapper-4.0.tar.gz#md5=78df3b40735e959479d9de34e4b8ba15
tar -xvzf virtualenvwrapper-*
python virtualenvwrapper-4.0/setup.py install
echo 'export WORKON_HOME=~/Envs' >> .bashrc # Change this directory if you don't like it
source $HOME/.bashrc
mkdir -p $WORKON_HOME
echo '. /usr/bin/virtualenvwrapper.sh' >> .bashrc
source $HOME/.bashrc

# Done!
# Now you can do: `mkvirtualenv foo --python=python2.7`
