pip and easy_install work on directory hierarchy of the running
python.

then  the idea (just the idea, not read sample)

python2.7 pip.py **** will install into python2.7 directories
python2.7 easy_install.py **** will install into python2.7 directories

python2.6 pip.py **** will install into python2.6 directories
python2.6 easy_install.py **** will install into python2.6 directories


For example (real this time) to install easy_install for your 2.7

wget http://peak.telecommunity.com/dist/ez_setup.py
python2.7 ez_setup.py

Probably because you run installed pip from python2.7 directory, that
certainly use python2.7 binary,
and then pip uninstall from python2.7 directories

Because you are no using the same pip/easy_install to install or
uninstall (or at least the python binary is not the same)
