Don't "su", run "su -" and everything will be much better.

It's not just the vars that aren't set up properly when you omit the "-" from 
the su command, either.  I always tell my students, "ALWAYS, use 'su -', even 
if you think you know better.

If the change of directory compels you to omit the "-", then run "pwd" 
before "su -", double-click the path, type "cd " and then middle-click your 
mouse (and press <ENTER>, of course). :)

Just to be entirely clear, sourcing in the environment variables still won't 
completely set things up right.  Some of the missing things can be subtle and 
hard to identify.  Always use "su -" and life will be much better for you.

HTH.
