conflicting versions of interpreters are quite seldom, at least in
Python-land. (That's perhaps because python has some community
processes that let's the developers know what will be enabled in the
next version, new keywords/syntax need normally imports from
__future__ *g*, e.g. taking a look at python 2.5 I can know what
keywords/changes will be enabled by default in 2.6)

Python usually is pretty well back-wards compatible. In Unix-practice
one just distributes the scripts/modules and uses the python that is
installed on the box. Guess the same thing applies more or less to
Ruby, albeit it's not yet standard on that many distributions as Python.

ipkg install python => you get the standard python and that's it.
