Step 3: Update your alias in your .bashrc

alias gcc='gcc44'

Step 4: Configure python 2.7.8

# cd python-2.7.8
# ./configure --prefix=/usr/local/python-2.7.8
# make -j 8
# make install

export PATH=$PATH:/usr/local/python-2.7.8/bin.........
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/python-2.7.8/lib
