+@subsubheading Using Python scripts on MacOS 10.3 or 10.4
+
+LilyPond binaries for MacOS X do not provide Python, but Python 2.4 or
+newer is required by @command{convert-ly}. Therefore, if you use MacOS
+10.3 or 10.4, you must install a newer Python version from
+@uref{http://python.org/download/}, then edit the first line of
+@command{convert-ly} and @command{lilypond-book} as follows: if the
+Python binary you just installed is in your @var{PATH}, the first line
+should be
+
+@example
+#!/usr/bin/env python
+@end example
+
+@noindent
+otherwise it should be
+
+@example
+#!@var{/path/to/newly_installed/python}
+@end example
