I have installed a python package slimit and I have cloned the source code from github.
I am doing changes to this package in my local folders which I want to test (often) but I don't want to do allways python setup.py install.
My folder structure is:
../develop/slimit/src/slimit (contains package files)
../develop/test/test.py
I'm using eclipse + pydev + python 2.7, on linux
Should I run eclipse with "sudo rights"?
Even better, is there a way to import the local development package into my testing script?
When you're working on a library you can use python setup.py develop instead of install. This will install the package into your local environment and keep it updated as you develop. 
To be clear, if you use develop you don't have to run it again when you change your source files.
