I think the alternatives system would be appropriate here. Or you
could use the 'divert' aspect of dpkg so that the 2.4 package diverts
the 2.3's /usr/bin/harvestman file when both are installed (vim uses
this to supply the desired 'vim' binary when you add the -gtk or
-python variants).

HarvestMan is an application, not a library, right? If so then I
think just one version is adequate. This relates to your question
about upstream recommending using the latest stable python (2.4.1). I
would suggest just providing one package ('harvestman') that depends
on python2.4.
If HarvestMan is also a library and provides an API that is intended
to be imported and used directly by other applications, then the
situation is different and you would be right in providing two
packages with no Conflicts. The difference is that some 4th and 5th
party application (that uses the python-harvestman library) may
require only python 2.3 or only 2.4 and you want to allow a debian
system to have both of those applications installed.
