Unable to runs scons getting import error

I have installed scons 2.3.2 and have python 2.4.

When I run scons, I am seeing the following error:

scons
Import failed. Unable to find SCons files in:
  /usr/bin/../engine
  /usr/bin/scons-local-2.3.2

                        ^
SyntaxError: invalid syntax

I did a find and found that SCons is present in /usr/lib/scons. I am not sure why scons is not able to pick it up.

What am I missing?

The problem (from the bottom of the traceback) is a Syntax error:

    p = self.stack[-1] if self.stack else self.default_table
                        ^
SyntaxError: invalid syntax

This is because you are running a version of Python that doesn't support conditional expressions:

Support for this syntax was added in 2.5, see the docs
