I want to use some packages (i.e., IPython or zdaemon), butI am doing this on a system (my university) that does not give me permissions for /usr/local, /usr/bin, or all these directories. Is there a way around it?
Use the --install-dir option.  You need to make sure this directory is in PYTHONPATH.  You may find the documentation helpful. 
Sure, you can use a configuration file that specifies an alternate installation directory, or use the --install-dir option. The standard place to put Python packages in your own user account is, I think, in $HOME/.local/ (if you're using Python 2.6). So for instance, pure-Python packages will wind up in $HOME/.local/lib/python2.6/site-packages/.
If your version of setuptools is recent enough to support it, also have a look at the --prefix option.
Other Option is using virtualenv to help, if available
$ virtualenv myenv $ source myenv/bin/activate (myenv)$ easy_install mycoolpackage
now it will end up in myenv subdir to re-activate, just call the source line above and to deactivate it, just close the terminal or (myenv)$ deactivate $
