Bug#501774: build needs to be done on lenny, due to python-support 0.90.0 and above

[Luke Kenneth Casson Leighton <luke.leighton@googlemail.com>]

there's an issue with building python .debs using python-support
0.90.0 or above, which screws up installations that would otherwise be
perfectly acceptable and compatible on lenny and squeeze (and i
wouldn't be surprised if they were compatible with etch as well).
the dependencies in pyjamas on python are absolutely minimal -
absolutely no libraries. even python2.4 is useable as the
python-to-javascript translator.
if there's anything that can be done about this, to ensure
installability across a wide range of debian platforms (and ubuntu as
well) that'd be great to hear about.
