That basically summarizes why I put the feature request for perlbrew
forward, so that it could encapsulate the usefulness of local::lib
within perlbrew. You shouldn't need to keep installing and compiling
perls.
rvm if you haven't tried it really works well(for ruby).

Here is a direct knock off of perlbrew called pythonbrew
https://github.com/utahta/pythonbrew#readme
Essentially all the commands are the same
such as
pythonbrew install 2.7.2
pythonbrew switch 2.7.2
It has implemented a few nice features.
Runs a named python file against specified and/or all pythons:
pythonbrew py -p 2.7.2 -p 3.2 test.py # Use the specified pythons
and then there virtual implementation.
Create isolated python environments (uses virtualenv):
pythonbrew venv init
pythonbrew venv create proj
pythonbrew venv list
pythonbrew venv use proj
pythonbrew venv delete proj
