Sounds like something went wrong with the env script, it's supposed to generate
a warning if you don't source it.  Which shell were you using when you sourced it?

Non-POSIX shells are not supported (in Poky at least).  Which is why csh/tcsh
isn't there.. but bash, ash, dash, zsh, etc all though work..  there is one
issue with zsh where it can't tell if you sourced it or not (which is why I'm
asking about the above.)

For csh/tcsh there is an unofficial patch to enable support -- but so far it's
been deemed to risky to included.
