python 2.7 may cause conflicts

[jam7]

There is pre-installed python 2.7 on chromium os.

When I try to install python 2.7 using chromebrew, it cause several errors on i686 environment. It is caused by pre-installed python 2.7. I needed to remove all /usr/local/lib/python2.7 and /usr/local/bin/python stuff to compile new python 2.7.
