Make your own Python 2.5 and put its bin directory first in your PATH.
Install latest setuptools into that Python.
Use that Python’s bin/easy_install to install virtualenv.
Read the repoze.bfg Introduction and perform the steps in the Installing repoze.bfg and Creating a repoze.bfg Project sections, using the bfg_zodb Paster template!!:
$ paster create -t bfg_zodb
Name your project FeedsTool.
Note
If you have trouble installing repoze.bfg due to compilation issues for lxml and libxml2, try the following command:
$ STATIC_DEPS=true easy_install lxml
This installs the lxml package directly, giving it options for getting a new, up-to-date version of libxml2.
Consider running the source bin/activate to make your shell environment wired to use the virtualenv.
Make sure you do the testing step and the startup step at the end of the “Creating a Project” section.
