Difficult to say without your PYTHONPATH value.

Assuming your PYTHONPATH is

/home/brian/webapps/test_dyn/lib/python2.7/site-packages

1/ paste is stable, copy the paste directory into 
/home/brian/webapps/test_dyn/lib/python2.7/site-packages
2/ paste is not stable, i.e. you're changing it from time to time, make 
a symbolic link to your dev paste directory within 
/home/brian/webapps/test_dyn/lib/python2.7/site-packages

you should now be able to import paste from anywhere.
