If you know that the machine contains `python` (whatever the version is)
you can use sys.version to check the system python's version. It can be
as simple as:
import sys
if int(sys.version[0]) > 1 or
(int(sys.version[0]) == 1 and int(sys.version[2] >= 5)):
# or you can start a subprocess instead,
# abusing import makes "if __name__ == '__main__':" magic not work
import MyMainProgram
else:
# parentheses guards for python 3
print ('script is only compatible with python version 1.5 and above')
Otherwise, if you cannot even rely on python being available, you may
need to use shell script.

That is indeed possible, however is there any reason why the server
don't upgrade its python version? CPython makes it easy to do parallel
installation of two different python version. If you can persuade the
machine administrator to install python2.6 as an altinstall; you can
simply change the hashbang line of your script to "#!/usr/bin/env
python2.6" and all is well.
