#29004 — conflicting installations of python

I installed python 2.7.3 using macports on Lion, and used port select python python27. However python version still shows 2.7.1.

Any ideas why is that happenning? And how to fix it?

Thanks in advance,

Macports installs its ports into a separate root.  You need to ensure 
that the macports bin directory comes first on your shell search path;  
by default, it is /opt/local/bin.  Try something like this:

    export PATH=/opt/local/bin:$PATH

Otherwise, use an alias or an absolute path:

    /opt/local/bin/python

Hi Ned, 

Thanks for your response, I think the path is fine, since which python outputs the location where macports should install python i.e. /opt/local/bin/python.

also 

port list active | fgrep python
python27                       @2.7.3          lang/python27

and

port location python27

Port python27 2.7.3_0 is installed as an image in:
/opt/local/var/macports/software/python27/python27-2.7.3_0.darwin_11.x86_64.tbz2


Another problem caused by this installation is that somehow it removes os.urandom module:

>>> import os
>>> os.urandom
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: 'module' object has no attribute 'urandom'

None of the above actually shows what is being executed when you type 
python.  What is the output from the following commands?

    which python
    ls -l $(which python)
    python

Looks like you are using a broken Python installation.
