Note that on Ubuntu (at least on 7.04) the default ~/.bashrc contains the following line:
 
# If not running interactively, don't do anything
[ -z "$PS1" ] && return

This results in different behavior of 'ssh somehost command' and 'ssh somehost' followed by 'command'.
So if your want to control PATH from .bashrc, make sure you delete this line.

This would explain why orted is found in an interactive shell while ompi startup can't find it. The strange thing is, that /usr/bin/orted is not found while /usr/local/bin/orted is. Usually /usr/bin is always in Ubuntu's PATH ...
