Installing Rails

I got rails working with some help from some online suggestions.
Here's somethings that I think helped:

• Initially just used Ubuntu gems to install rails. When I tried to start the server it complained it needed a newer rubygems (gem).
• Install new rubygems from the website. Hopefully a future Ubuntu upgrade to rubygems won't wipe this out.
• Default page that shows server configuration had an error complaining about missing sqlite3 file.
• I don't know if the sqlite3-ruby gem was installed already or not, but I think it may have been.
• sudo aptitude install libsqlite3-dev libsqlite3-ruby helped, but I don't know which did it.

I did other things too, but I'm not sure which are were necessary. I guess I'll get to find out when I install on the Fedora ami :-)
