AFAICT it requires nothing but python 2.4 and the standard libraries.

The "hashbang" at the beginning of the script reads:
#!/usr/bin/env python

This is a common trick to avoid needing to know where the python
interpreter lives.  Two things could go wrong with that:

1) You might not have "env" installed, or it might be somewhere
other than /usr/bin.  (It's provided by gnu coreutils so i'd be amazed
if your distro doesn't have it.)
Try this: 
env --version
which env

2) If you have multiple python versions installed, it's likely 
that 'python' is a symlink to the wrong one.  youtube-dl is hardcoded
to exit if the version is less than 2.4, with the message
'Error: Python 2.4 or later needed to run the program'

Try this:

ls -l `which python`

and/or

/usr/bin/env python -V

... and see what that tells you.

If you need to keep around an earlier version of python as the default
python, a workaround is to invoke 2.4 directly,
typically something like:

python2.4 /path/to/youtube-dl ...

If that works, wrap it up as a shell alias for convenience,
e.g. in .bashrc:

alias youtube-dl="/usr/bin/python2.4 /path/to/youtube-dl"
