The problem is I have already installed the python2.3.
But MPI program Or Cluster application they are default set to use the python 2.4.So I need to redirect from python2.4 to python2.3.
Using Soft Link we can resolve that problem.
For python2.3 it is working perfectly for python2.3.
# /usr/bin/env python2.3
Python 2.3.4 (#1, Feb 18 2008, 17:16:53)
[GCC 3.4.6 20060404 (Red Hat 3.4.6-9)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
To Resolve these problem for python2.4
1)create the soft link for python2.4 to python2.3
-s soft link
-f force
#ln -sf /usr/bin/python2.3 /usr/bin/python2.4
Then try it the problem has been cleared
/usr/bin/env: python2.4: No such file or directory
/usr/bin/env: python2.4: Permission denied
