How to install Python 2.7 on Ubuntu 9.10

Question

Now we're developing our software on the customer side, and there is:

maestro@UIServer:~$ cat /etc/lsb-release 
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=9.10
DISTRIB_CODENAME=karmic
DISTRIB_DESCRIPTION="Ubuntu 9.10"

system is installed. We're not allowed to upgrade this system to a newer version, but we need to use Python 2.7 in our project.

E.g. we have to use pymorphy2 package, but when we're trying to import it into project, we get:

>>> import pymorphy2
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python2.7/site-packages/pymorphy2/__init__.py", line 3, in <module>
    from .analyzer import MorphAnalyzer
  File "/usr/local/lib/python2.7/site-packages/pymorphy2/analyzer.py", line 10, in <module>
    from pymorphy2 import opencorpora_dict
  File "/usr/local/lib/python2.7/site-packages/pymorphy2/opencorpora_dict/__init__.py", line 4, in <module>
    from .storage import load_dict as load
  File "/usr/local/lib/python2.7/site-packages/pymorphy2/opencorpora_dict/storage.py", line 24, in <module>
    from pymorphy2.utils import json_write, json_read
  File "/usr/local/lib/python2.7/site-packages/pymorphy2/utils.py", line 5, in <module>
    import bz2
ImportError: No module named bz2

Ok, we're trying to install libbz2-dev:

sudo apt-get install libbz2-dev

end getting this:

ValueError: /usr/bin/python does not match the python default version. It must be reset to point to python2.6
dpkg: error processing python-pip (--configure):
 subprocess installed post-installation script returned error exit status 1
Errors were encountered while processing:
 python-pip
E: Sub-process /usr/bin/dpkg returned an error code (1)

How to avoid this problem?

Thanks in advance!

Download python, build and install using :

$ ./configure
$ make
$ make install

I am assuming you have build-essential installed or at least gcc. You can customize installation by passing prefix=/path/where/you/want/python/installed and other flags to make.
