I see what you mean, having started my fedora8-live image under virtualbox. -g support is apparently not there with this distribution, oddly enough. Perhaps you should post your question on a fedora support forum.
Under the live cd (hence probably with a smaller selection of available packages than you have), if I try the following at the interactive python prompt, I am getting "No module named Tkinter" import pydoc pydoc.gui() You probably discovered this already, but you can at least launch "pydoc -p 1234" and view the python doc by pointing your browser to localhost:1234. The small tkinter gui normally invoked by "-g" would add a handy search box to this viewer... The main python doc page points to the following search link: http://starship.python.net/crew/theller/pyhelp.cgi which looks similar enough to what "pydoc -g" would offer. -- http://mail.python.org/mailman/listinfo/python-list
