installation of 0.4.11~rc1 fails with Python 2.4

[Mark Lee]

I'm running Python 2.4.4 on Gentoo Linux, and `python setup.py install` fails with the following:

sh: apr-config: command not found
Traceback (most recent call last):
  File "setup.py", line 161, in ?
    (apr_includedir, apr_ldflags) = apr_build_data()
  File "setup.py", line 81, in apr_build_data
    includedir = apr_config("--includedir")
  File "setup.py", line 66, in apr_config
    res = run_cmd(cmd, arg)
  File "setup.py", line 51, in run_cmd
    cmd, arg, status, code)
  File "setup.py", line 32, in __init__
    super(CommandException, self).__init__(self.message)
TypeError: super() argument 1 must be type, not classobj

I assume the problem is that in Python 2.4.x, exceptions are derived from old-style classes, and therefore super() doesn't work.
