[chef] chef install from gem to Ubuntu not in path

[Edward Sargisson < >]

Hi all,
I'm running Ubuntu 10.10 on my desktop and sudo gem install chef ran
successfully but knife and chef-client didn't appear in the default
path.

I'm not familiar enough with how ruby and gem put things into the path
(symlinks in /usr/bin?) so could somebody please point me a suitable
document to figure this out?

Many thanks,
Edward
