This is easily done. I install duplicity locally into a folder in my home 
folder (because I'm wary of using anything besides the Linux distribution's 
package manager that wants to install to root), so you can use this to install 
duplicity to some other locations as well.

Here's what I do:

* I have an extensive bash alias that sets up the various PATH variables to 
what they need to be. I've cut out all but the ones you'll use:
export PREFIX="$HOME/opt" &&\
export PATH="$PATH:$PREFIX/bin" &&\
export 
PYTHONPATH="$PYTHONPATH:$PREFIX/lib/python:$PREFIX/lib/python2.5/site-packages" 
&&\
export MANPATH="$MANPATH:$PREFIX/man:$PREFIX/share/man"
* The ones I am 100% positive duplicity uses is PYTHONPATH and MANPATH. PATH is 
optional, but you might want it anyway, just so you can run "duplicity" without 
the full path (as shown in duplicity's README). Be sure to change "python2.5" 
to "python2.4" if you're still using that version.
* You'll want to also adjust the PREFIX path to point to a different directory 
for each version of duplicity. The other variables all use PREFIX, so that 
makes it easy to change around.
* When installing duplicity, make sure $PREFIX is set to the right folder, and 
run:
python setup.py install --prefix=$PREFIX

Let me know if you have any other questions.
