Default python /usr/bin/python instead of /usr/local/bin/python

Question

I have both python2.6 and python2.7 installed in my CentOS box. python2.6 is installed at /usr/bin/python and i have installed python2.7 from source at location /usr/local/bin/python

after the installation my default python is changed to python2.7 instead of pythn2.6 at /usr/bin, I want to use python 2.6 at /usr/bin/python. I have tried following things already nothing worked.

1. I have created symlink and made it point to python 2.6 at /usr/bin
2. I have modified my default python path in .bash_profile and but that still doesn't work

Please let me know how can i have python 2.7 installed along with 2.6 installed and python 2.6 as my default version. I have the same thing working with my arch linux box, but this doesn't work with my centos box.

Attaching my .bash_profile,

# .bash_profile

export _BASH_PROFILE=1

# Get the aliases and functions
if [ -z "$_BASHRC" ]; then
        . ~/.bashrc
fi

unset _BASH_PROFILE

# User specific environment and startup programs

PATH=$PATH:$HOME/bin
BASH_ENV=$HOME/.bashrc
USERNAME=""

export USERNAME BASH_ENV PATH

export user=$(/usr/bin/whoami)
export WK_PORT=8086
export WK_PATH=ADC

# For DEV accounts change PYDOC_PORT value to 7400 + webkit number. For
# example WK23 would be port number 7423
export PYDOC_PORT=7464


alias serve="python -m SimpleHTTPServer"


unset _BASH_PROFILE

# User specific environment and startup programs

PATH=$PATH:$HOME/bin
BASH_ENV=$HOME/.bashrc
USERNAME=""

export USERNAME BASH_ENV PATH

export user=$(/usr/bin/whoami)
export WK_PORT=8086
export WK_PATH=ADC

# For DEV accounts change PYDOC_PORT value to 7400 + webkit number. For
# example WK23 would be port number 7423
export PYDOC_PORT=7464


alias serve="python -m SimpleHTTPServer"


PYTHONPATH="$PYTHONPATH:/usr/bin/python"

I had the same problem. The following command fixed it:

sudo ln -sf /usr/bin/python /usr/local/bin/python

This will make a symbolic link from /usr/local/bin/python --> /usr/bin/python. Referred from here
