to double check things I logged back out and my PATH is now back to:

/home/gps/opt/jdk1.6.0_06/bin:/home/gps/opt/hg:/sbin:/home/gps/bin:/home/gps/opt/jdk1.6.0_06/bin:/home/gps/opt/hg:/sbin:/home/gps/bin:/usr/local/bin:/usr/bin:/bin:/usr/X11R6/bin

again with everything being added twice. This is really strange. Any 
thoughts?
